Adjustable step-down controller with synchronous rectification

Features

■ Input voltage range from 1.8 V to 14 V

■ Supply voltage range from 4.5 V to 14 V

■ Adjustable output voltage down to 0.6 V with

±0.8% accuracy over line voltage and

temperature (0°C~125°C)

■ Fixed frequency voltage mode control

■ tON lower than 100 ns

■ 0% to 100% duty cycle

■ Selectable 0.6 V or 1.2 V internal voltage

reference

■ External input voltage reference

■ Soft-start and inhibit

■ High current embedded drivers

■ Predictive anti-cross conduction control

■ Selectable uvlo threshold (5 V or 12 V BUS)

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

sense overcurrent protection

■ Switching frequency programmable

from 100 kHz to 1 MHz

■ Master/slave synchronization with 180° phase

shift

■ Pre-bias start up capability (L6730)

■ Selectable source/sink or source only

capability after soft-start (L6730)

■ Selectable constant current or hiccup mode

overcurrent protection after soft-start (L6730B)

■ Power Good output with programmable delay

■ Overvoltage protection with selectable

latched/not-latched mode

■ Thermal shut-down

■ Package: HTSSOP20

Applications

■ High performance / high density DC-DC

modules

■ Low voltage distributed DC-DC
