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.
