STBB3JCC Overview
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 efficiency driving high brightness white LED in constant current mode. The device can operate with input voltages higher...
