Description: Synchronous Step-Down PWM Controller

Features

* Three Integrated Synchronous Buck PWM Controllers - Internal Bootstrap Diodes - Independent Programmable Output Voltage - Independent Soft-Starting and Tracking
* Power-Good Indicator
* Light Load Efficiency Enhancement - Low Ripple Diode Emulation Mode with Pulse Skipping

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 ISL9443 offers programmable soft-start and tracking functions for ease of supply rail sequencing and integrated UV/OV/OC/OT protections in a space cons
