High currents switching at 200kHz are pre-sent in the application and their effect on ground plane voltage differentials must be understood and mini-mized.1). The high power parts of the circuit should be laid out first. A ground plane should be used, the number and position of ground plane interruptions should be such as to not unnecessarily compromise ground plane integrity. Isolated or semi-isolated areas of the ground plane may be deliberately introduced to constrain ground currents to particular areas, for example the input capacitor and bottom FET ground.2). The loop formed by the Input Capacitor(s) (Cin), the Top FET (Q1) and the Bottom FET (Q2) must be keptas small as possible. This loop contains all the high current, fast transition switching. Connections should be as wide and as short as possible to minimize loop inductance. Minimizing this loop area will a) reduce EMI, b) lower ground injection currents, resulting in electrically “cleaner” grounds for the rest of the system and c) minimize source ringing, resulting in more reli-able gate switching signals.3). The connection between the junction of Q1, Q2 and the output inductor should be a wide trace or copper region. It should be as short as practical. Since this connection has fast voltage transitions, keeping this connection short will minimize EMI. The connection between the output inductor and the sense resistor should be a wide trace or copper area, there are no fast voltage or current transitions in this connection and length is not so important, however adding unnec-essary impedance will reduce efficiency.Vout12V IN5VVo Lin1Vo Lin25V4uH5mOhm+Cout+Cin10Q 20.1uFQ 3+Cout Lin12.32kQ 4+Cout Lin21.00kR B 1RA1RA2R B 2+Cin LinSC1182/3AGND 1V C C 5O V P 6P W R G O O D 7CS-8C S +9P G N D H 10DH 11BSTH 15EN 16VO SENSE17VID418VID319VID220VID121VID022D L13P G N D L12B S T L 14GATE224GATE12L D V O 23L D O S 13L D O S 24Q 10.1uFHeavy lines indicate high current paths.are not required.

PGNDH and PGNDL should be returned to the ground plane close to the package.The AGND pin should be connected to the ground side of (one of) the output capacitor(s). If this is not possible, the AGND pin may be connected to the ground path between the Output Capacitor(s) and the Cin, Q1, Q2 loop. Under no circumstances should AGND be returned to a ground inside the Cin, Q1, Q2loop.6) Vcc for the SC1182/3 should be supplied from the5V supply through a 10Ω resistor, the Vcc pin should be decoupled directly to AGND by a 0.1µF ceramic capacitor, trace lengths should be as short as possi-ble.7) The Current Sense resistor and the divider across it should form as small a loop as possible, the traces running back to CS+ and CS- on the SC1182/3should run parallel and close to each other. The 0.1µF capacitor should be mounted as close to the CS+ and CS- pins as possible.8) Ideally, the grounds for the two LDO sections should be returned to the ground side of (one of) the output capacitor(s).Currents in various parts of the power sectionAugust 25, 1998COMPONENT SELECTIONSWITCHING SECTION OUTPUT CAPACITORS - Selection begins with the most critical component. Because of fast transient load current requirements in modern microprocessor core supplies, the output capacitors must supply all transient load current requirements until the current in the output inductor ramps up to the new level. Output capacitor ESR is therefore one of the most important criteria. The maximum ESR can be simply calculated from:stepcurrent Transient I excursion voltage transient Maximum V WhereI V R t t tt ESR==≤Each CapacitorTotal Technology C (µF)ESR (m Ω)Qty.Rqd.C (µF)ESR (m Ω)Low ESR Tantalum 330606200010OS-CON3302539908.3Low ESR Aluminum150044575008.8()O IN tESR V V I CR L −≤OSCIN L f L 4V I RIPPLE ⋅⋅=INO)on (DS 2O COND V V cycle duty = whereR I P ≈δδ⋅⋅=2IN O SW 10V I P −⋅⋅=4f )t t (V I P OSCf r IN O SW ⋅+⋅⋅=OSCIN RR RR f V Q P ⋅⋅=For example, to meet a 100mV transient limit with a 10A load step, the output capacitor ESR must be less than 10m Ω. To meet this kind of ESR level, there are three available capacitor technologies.The choice of which to use is simply a cost/perfor-mance issue, with Low ESR Aluminum being the cheapest, but taking up the most space.INDUCTOR - Having decided on a suitable type and value of output capacitor, the maximum allowable value of inductor can be calculated. Too large an in-ductor will produce a slow current ramp rate and will cause the output capacitor to supply more of the tran-sient load current for longer - leading to an output volt-age sag below the ESR excursion calculated above.The maximum inductor value may be calculated from:The calculated maximum inductor value assumes 100%duty cycle, so some allowance must be made. Choosing an inductor value of 50 to 75% of the calculated maxi-mum will guarantee that the inductor current will rampfast enough to reduce the voltage dropped across the ESR at a faster rate than the capacitor sags, hence en-suring a good recovery from transient with no additional excursions.We must also be concerned with ripple current in the output inductor and a general rule of thumb has been to allow 10% of maximum output current as ripple current.Note that most of the output voltage ripple is produced by the inductor ripple current flowing in the output ca-pacitor ESR. Ripple current can be calculated from:Ripple current allowance will define the minimum per-mitted inductor value.POWER FETS - The FETs are chosen based on sev-eral criteria with probably the most important being power dissipation and power handling capability.TOP FET - The power dissipation in the top FET is a combination of conduction losses, switching losses and bottom FET body diode recovery losses.a) Conduction losses are simply calculated as:b) Switching losses can be estimated by assuming a switching time, if we assume 100ns then:or more generally,c) Body diode recovery losses are more difficult to esti-mate, but to a first approximation, it is reasonable to as-sume that the stored charge on the bottom FET body diode will be moved through the top FET as it starts to turn on. The resulting power dissipation in the top FET will be:To a first order approximation, it is convenient to only consider conduction losses to determine FET suitability.For a 5V in; 2.8V out at 14.2A requirement, typical FET losses would be:August 25, 1998)1(R I P )on (DS 2O COND δ−⋅⋅=FET typeR DS(on) (m Ω)P D (W)Package BUK556H 22 2.48TO220IRL22037.00.79D 2PAK Si441013.51.53SO-8FET type R DS(on) (m Ω)P D (W)Package BUK556H 221.95TO220IRL22037.00.62D 2PAK Si441013.51.20SO-8BOTTOM FET - Bottom FET losses are almost entirely due to conduction. The body diode is forced into con-duction at the beginning and end of the bottom switch conduction period, so when the FET turns on and off,there is very little voltage across it, resulting in lowswitching losses. Conduction losses for the FET can be determined by:For the example above:Each of the package types has a characteristic thermal impedance, for the TO-220 package, thermalimpedance is mostly determined by the heatsink used.For the surface mount packages on double sided FR4, 2oz printed circuit board material, thermal impedances of 40o C/W for the D 2PAK and 80oC/W for the SO-8 are readily achievable. The corresponding temperature rise is detailed below:Temperature rise (oC)FET type Top FETBottom FET BUK556H 49.6(1)39.0(1)IRL220331.624.8Si4410122.496(1) With 20oC/W HeatsinkIt is apparent that single SO-8 Si4410 are not adequate for this application, but by using parallel pairs in each po-sition, power dissipation will be approximately halved and temperature rise reduced by a factor of 4.INPUT CAPACITORS - since the RMS ripple currentin the input capacitors may be as high as 50% of the output current, suitable capacitors must be chosen ac-cordingly. Also, during fast load transients, there may be restrictions on input di/dt. These restrictions require useable energy storage within the converter circuitry,either as extra output capacitance or, more usually,additional input capacitors. Choosing low ESR input capacitors will help maximize ripple rating for a given size.August 25, 1998OUTLINE DRAWINGJEDEC MS-013ADB17104B。
