DATASHEET ISL9440, ISL9440A, ISL9441 Triple, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller FN6383 Rev 2.00 February 9, 2015 The ISL.

Features

* PART NUMBER ISL9440 ISL9440A ISL9441 EARLY WARNING YES YES NO SWITCHING FREQUENCY (kHz) 300 600 300 Features
* Three integrated synchronous buck PWM controllers - Internal bootstrap diodes - Internal compensation - Internal soft-start
* Independent control for each regulator and

Applications

* Each output is adjustable down to 0.8V. The PWMs are synchronized at 180° out of phase thus reducing the RMS input current and ripple voltage. The ISL9440, ISL9440A and ISL9441 offer internal soft-start, independent enable inputs for ease of supply rail sequencing, and integrated UV/OV/OC/OT protec
