STBB3JCC Datasheet (STMicroelectronics) - high efficiency single inductor buck-boost DC-DC converter and high brightness WLED driver

STBB3JCC, high efficiency single inductor buck-boost DC-DC converter and high brightness WLED driver

The STBB3JCC is a fixed frequency, high efficiency, buck-boost DC-DC converter which provides output voltages from 1.2 V to 5.5 V starting from input voltage from 1.8 V to 5.5 V.

Thanks to very low sensing voltage, only 100 mV and very low RDS(on) of integrated power MOSFET, it achieves very high ef
