ISL9444, Synchronous Step-Down PWM Controller

DATASHEET ISL9444 Triple, 180° Out-of-Phase, Synchronous Step-Down PWM Controller FN7665 Rev 3.00 May 29, 2012 The ISL9444 is a triple-output synch.
PIN NAME FUNCTION 1 PFO Output of the auxiliary power monitor.

Features

* Three Integrated Synchronous Buck PWM Controllers - Internal Bootstrap Diodes - Independent Programmable Output Voltage - Independent Power-Good Indicators, Soft-Starting and Tracking
* Power Failure Monitor
* Light Load Efficiency Enhancement - Low Ripple Diode Emulation M

Applications

* Each output is adjustable down to 0.7V. The PWMs are synchronized at 180° out-of-phase, thus reducing the input RMS current and ripple voltage. The ISL9444 offers independent power-good indicators, programmable soft-start and tracking functions for ease of supply rail sequencing and integrated UV/O
