The device integrates 130m ΩFEATURES• 3A Output CurrentPACKAGE REFERENCEABSOLUTE MAXIMUM RATINGS (1)ELECTRICAL CHARACTERISTICS (continued) V IN = 12V, T A = +25°C, unless otherwise noted.BLOCK DIAGRAMAPPLICATIONS INFORMATIONCOMPONENT SELECTIONSetting the Output VoltageThe output voltage is set using a resistiveIN S switching frequency, and ∆I L is the peak-to-peak inductor ripple current.Choose an inductor that will not saturate under the maximum inductor peak current. The peak inductor current can be calculated by:The input capacitor can be electrolytic, tantalum or ceramic. When using electrolytic or tantalum capacitors, a small, high quality ceramic capacitor, i.e. 0.1µF, should be placed as close to the IC as possible. When using ceramicaffect the stability of the regulation system. The MP2367 can be optimized for a wide range of capacitance and ESR values.Compensation ComponentsMP2367 employs current mode control for easy compensation and fast transient response. The system stability and transient response are controlled through the COMP pin. COMP pin isIn this case, a third pole set by the compensation capacitor (C6) and theTable 1—Compensation Values for Typical Output Voltage/Capacitor CombinationsTo optimize the compensation components for conditions not listed in Table 1, the following procedure can be used.1. Choose the compensation resistor (R3) to set the desired crossover frequency. Determine theExternal Bootstrap DiodeIt is recommended that an external bootstrap diode be added when the system has a 5V fixed input or the power supply generates a 5V output.
