LM3753 Description
The LM3753 and LM3754 are full featured single-output dualphase voltage-mode synchronous PWM buck controllers. They can be configured to control from 2 to 12 interleaved power stages creating a single high power output. Both controllers utilize voltage-mode control with input voltage feedforward for high noise immunity.
