The LM3754 is a full featured single-output dual-phase voltage-mode synchronous PWM buck controller. It can be configured to control from 2 to 12 interleaved power stages creating a single high power output. This controller utilizes voltage-mode control with input voltage feed-forward for high noise immunity. An internal average current loop forces real time current sharing between phases during load transients.
The LM3754 supports adjustable Soft-Start. The Soft-Start function can only drive the output upwards – it will not pull it down, therefore, pre-biased loads will not be discharged. Available in the 5 mm x 5 mm thermally enhanced 32-lead WQFN package with a thermal pad.
