ISL6402, Step-Down PWM and Single Linear Controller

DATASHEET ISL6402 300kHz Dual, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller FN9123 Rev 3.00 Nov 8, 2004 The ISL6402 is a high-performance, triple-output controller optimized for converting wall adapter, battery or network intermediate bus DC input supplies into the system supply voltages required for a wide variety of applications.

Each output is adjustable down to 0.8V.

The two PWMs are synchronized 180o out of phase reducing the RMS input current and ripple voltage.

ISL6402 Features

* An adjustable overcurrent protection circuit monitors the output current by sensing the voltage drop across the lower MOSFET. Hiccup mode overcurrent operation protects the DC-DC components from damage during output overload/short circuit conditions. Each PWM has an independent logic-level shutdown
