Overview: DATASHEET ISL9440B, ISL9440C Triple Step-Down PWM and Single Linear Controller with Programmable Soft-Start FN6799 Rev 4.00 February 18, 2016 The ISL9440B and ISL9440C are quad-output synchronous buck controllers that integrate three PWM controllers and one 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 ISL9440B and ISL9440C offer programmable 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. An early warning function is offered to output a logic signal to warn the system to back up data when input voltage falls below a certain level. The ISL9440B and ISL9440C utilize internal loop compensation to keep minimum peripheral components for compact design and a low total solution cost. These devices are implemented with current mode control with feed-forward to cover various applications even with fixed internal compensations.
This datasheet includes multiple variants, all published together in a single manufacturer document.
