LM3753/54 Scalable 2-Phase Synchronous Buck Controllers with Integrated FET Drivers and Linear Regulator Controller LM3753/54 December 14, 2009 Scalable 2-Phase Synchronous Buck Controllers with Integrated FET Drivers and Linear Regulator Controller General 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. An internal average current loop forces real time current sharing between phases during load transients. The LM3753 supports a Tracking function, while the LM3754 supports adjustable Soft-Start.
