Triple, 180° Out-of-Phase, Synchronous Step-Down PWM Controller ISL9443 The ISL9443 is a triple-output synchronous buck controller that integrates three PWM controllers which are fully 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.
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/O...
