LM3753 Description
Not Remended 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.
