NOTES 1Settling Time is defined as the time elapsed from the application of a perfect step input to the time when the output has entered and remained within a specified error band symmetrical about the final value. This parameter includes propagation delay, slew time, overload recovery, and linear settling times. Specifications subject to change without notice.

PRODUCT DESCRIPTION The AD8015 is a wide bandwidth, single supply transimpedance amplifier optimized for use in a fiber optic receiver circuit. It is a complete, single chip solution for converting photodiode current into a differential voltage output. The 240 MHz bandwidth enables AD8015 application in FDDI receivers and SONET/SDH receivers with data rates up to 155 Mbps. This high bandwidth supports data rates beyond 300 Mbps. The differential outputs drive ECL directly, or can drive a comparator/ fiber optic post amplifier. In addition to fiber optic applications, this low cost, silicon alternative to GaAs-based transimpedance amplifiers is ideal for systems requiring a wide dynamic range preamplifier or singleended to differential conversion. The IC can be used with a standard ECL power supply (–5.2 V) or a PECL (+5 V) power supply; the common mode at the output is ECL compatible. The AD8015 is available in die form, or in an 8-pin SOIC package.

Product Specification
SG6105A
DESCRIPTION
SG6105A controller is designed for switching-mode power supplies for desktop PCs. It provides all the functions necessary to monitor and control the output of the power supply. Remote ON/OFF control, power–good circuitry, and protection features against over-voltage and over-power are implemented. It directly senses all the output rails for OVP without the need for external dividers. An innovative AC-signal sampling circuitry provides a sufficient power-down warning signal for PG.

Function
Remote on/off logic input for CPU or controller. Turn on/off the PWM output after the 7.5ms / 26ms delay. PSON = 0, the main SMPS is operational. PSON =1, the main SMPS is off and the latch is reset. 3.3V over-voltage/under-voltage control sense input. 5V over-voltage/under-voltage control sense input. Over-power sense input. This pin is connected to driver transformer or the Output of current transformer. When not in use, this pin should be grounded. AC fail detection, detect main AC voltage under-voltage and/or failure. The protection input for negative Output, such as –12V and/or –5V. Trip voltage = 2.1V. 12V over-voltage/under-voltage control sense input. The totem-pole Output drivers of push-pull PWM. The Output are enabled (low) only when the NAND gate inputs are high. The maximum duty cycle on an Output (OP1 or OP2) is 46%. Power-good logic output, 0 or 1 (open-collector). PG = 1, the power is good for operation. The PG delay is 300ms. Output for second converter regulation loop. Reference comparison input for second converter regulation loop, 2.5V. Reference comparison input for first converter regulation loop, 2.5V. Output for first converter regulation loop. Ground. Error amplifier Output and the input of the PWM comparator. The negative input of error amplifier. The positive input of error amplifier is a 2.5V reference voltage. The soft-start, settable through an external capacitor. The current source output at this pin is 8µA and the voltage is clamped at 2.5V.
