AIC1568 - 4-bit DAC/ Simple PWM Power Regulator

Datasheet Summary

Description

The AIC1568 is a high power, high efficiency switching regulator controller optimized for high performance microprocessor applications.

It is designed to drive an N-channel MOSFET in a standard buck topology.

Features

  • a 11MHz bandwidth and 6V/µS slew rate, which enables high converter bandwidth for fast transient response. The AIC1568 provides adjustable over current and short circuit protections. It senses the output current across the on resistance of the N-channel MOSFET without an external low value sense resistor. It also monitors the output voltage with a window comparator and issues a power good signal when the output is within 10% of the rated output voltage.
