LM3753 Product details

Description

Not Recommended for New Designs See LM3754 The LM3753 is a full featured single-output dualphase 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 LM3753 supports a Tracking f
