LM3753 Overview
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.
Key Features
- Wide input voltage range of 4.5V to 18V
- Up to 12 channels for 300A load
- System accuracy better than 1%
- 0.6V to 3.6V output voltage range
- Switching frequency from 200 kHz to 1 MHz
- Phase current sharing ±12% max over temperature
- Integrated 4.35V ±2.3% LDO
- Inductor DCR or sense resistor current sensing
- Interleaved switching for low I/O ripple current
- Integrated synchronous NFET drivers
