L6730B

Adjustable step-down controller with synchronous rectification

Features

■ Input voltage range from 1.8V to 14V

■ Supply voltage range from 4.5V to 14V

■ 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

■ tON lower than 100ns

■ 0% to 100% duty cycle

■ Selectable 0.6V or 1.2V internal voltage

reference

■ External input voltage reference

■ Soft-start and inhibit

■ High current embedded drivers

■ Predictive anti-crossconduction control

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

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

sense over-current-protection

■ Switching frequency programmable from

100kHz to 1MHz

■ 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

■ Over voltage 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

■ niPOL converters

■ DDR memory supply

■ DDR memory bus termination supply
