Overview

DATASHEET ISL6440 300kHz Dual, 180° Out-of-Phase, Step-Down PWM Controller FN9040 Rev 2.
00 Oct 4, 2005 The ISL6440 is a high-performance, dual-output PWM 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.
The ISL6440 incorporates several protection features.
An adjustable overcurrent protection circuit monitors the output current by sensing the voltage drop across the lower MOSFET.
Hiccup mode overcurrent operation protects ...
