The APW6021A provides power control and protection for high-performance, graphics-intensive microprocessor and computer applications. It integrates a voltage-mode PWM controller and three linear controllers, as well as monitoring and protection functions. The IC provides four output voltages and has ±1% static regulation. It also includes a digital-to-analog converter (DAC) that adjusts the core PWM output voltage and linear control with soft-start function for the AGP bus power. The other two linear regulators provide fixed output voltages.
The APW6021A is a power control and protection IC designed for high‑performance, graphics‑intensive microprocessor and computer applications. It integrates a voltage‑mode PWM controller, three linear regulators, monitoring and protection functions in a 28‑pin SOIC package.
The document provides electrical parameters, pin descriptions, mechanical dimensions, and reliability test data, enabling designers to implement the chip for core, AGP bus, and memory voltage regulation with selectable output ranges and external resistor‑adjustable linear outputs.
| Supply Voltage (VCC) | 15 V |
|---|---|
| Boot Voltage (VBOOT) | 15 V |
| Operating Ambient Temperature | 0 °C to 70 °C |
| Synchronous PWM Frequency (nominal) | 200 kHz |
Connecting a resistor from the FAULT/RT pin to ground increases the frequency, while a resistor to VCC decreases it.
