Voltage mode PWM controller

with bootstrap anti-discharging system

Features

■ Input voltage range from 1.8V to 18V

■ Supply voltage range from 4.5V to 18V

■ Adjustable output voltage down to 0.6V with

±0.8% accuracy over line voltage and

temperature (0°C~125°C)

■ Fixed frequency voltage mode control

■ 0% to 100% duty cycle

■ External input voltage reference

■ Soft-start and inhibit

■ Bootstrap anti-discharging system

■ High current embedded drivers

■ Predictive anti-cross conduction control

■ Programmable high-side and low-side RDS(on)

sense over-current-protection

■ Sink current capability

■ Selectable switching frequency 250KHz/

500KHz

■ Power good and synch available with L6725A

■ Pre-bias start up capability

■ Over voltage protection

■ Thermal shut-down
