ISL6522, Buck and Synchronous Rectifier

® Data Sheet November 2002 ISL6522 FN9030.3 Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller The ISL6522 provides complete control and protection for a DC-DC converter optimized for high-performance microprocessor applications.

It is designed to drive two N-Channel MOSFETs in a synchronous rectified buck topology.

The ISL6522 integrates all of the control, output adjustment, monitoring and protection functions into a single package.

The output voltage of the converter ca

ISL6522 Features

* a 15MHz gain-bandwidth product and 6V/µs slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0

* 100%. The ISL6522 protects against overcurrent conditions by inhibiting PWM operation. The ISL6522 monitors the current by usi
