STBB3JCC Overview
Key Specifications
Mount Type: Surface Mount
Pins: 20
Operating Voltage: 3.6 V
Max Voltage (typical range): 5.5 V
Description
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.
Key Features
- 100 mV feedback signal
- Input voltage range from 1.8 V to 5.5 V
- 2 A output current at 3.3 VOUT in buck mode (VIN= 3.6 V to 5.5 V)
- 800 mA output current at 3.3 VOUT in boost mode (VIN ≥ 2.0 V)
- Typical efficiency higher than 94%
