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. 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. The LM3753 Tracking is always enabled, so the output is controlled both up and down. The Soft-Start function on the LM3754 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 LLP package with a thermal pad.
