ST L6730/L6730B Manual
Update: 28 September, 2023
L6730 and L6730B are adjustable step-down controllers with synchronous rectification. They have an input voltage range from 1.8V to 14V and a supply voltage range from 4.5V to 14V. The adjustable output voltage can go down to 0.6V with ±0.8% accuracy over line voltage and temperature (0°C~125°C). They feature fixed frequency voltage mode control, tON lower than 100ns, and 0% to 100% duty cycle. They offer selectable 0.6V or 1.2V internal voltage reference or external input voltage reference. They have soft-start and inhibit functions, high current embedded drivers, and predictive anti-crossconduction control. They also have 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, and master/slave synchronization with 180° phase shift. The L6730 has pre-bias start up capability and selectable source/sink or source only capability after soft-start. The L6730B has selectable constant current or hiccup mode overcurrent protection after soft-start. They both have power good output with programmable delay, over voltage protection with selectable latched/not-latched mode, and thermal shut-down. They are suitable for high performance / high density DC-DC modules, low voltage distributed DC-DC, niPOL converters, DDR memory supply, and DDR memory bus termination supply.
