Overview
DATASHEET ISL9440, ISL9440A, ISL9441 Triple, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller FN6383 Rev 2.
00 February 9, 2015 The ISL9440, ISL9440A and ISL9441 are quad-output synchronous buck controllers that integrate 3 PWM controllers and 1 low drop-out linear regulator controller, which are full featured and designed to provide multi-rail power for use in products such as cable and satellite set-top boxes, VoIP gateways, cable modems, and other home connectivity products as well as a variety of industrial and general purpose 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 protections in a space conscious 5mmx5mm QFN package.
The ISL9440 and ISL9440A offers an early warning function to output a logic signal to...
