STBB3JCCR (STMICROELECTRONICS)
ИС управления питанием, понижающий повышающий DC/DC преобразователь 2A, 1.8В до 5.5В вход, 2.4МГц
The STBB3JCCR is a fixed frequency high efficiency buck-boost DC-DC Converter which provides output voltage from 1.2 to 5.5V starting from input voltage from 1.8 to 5.5V. Thanks to very low sensing voltage, only 100mV 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 than, equal to or lower than the output voltage making the product suitable for cell lithium-Ion applications where the output voltage is within the battery voltage range. The MODE pin allows the selection between auto mode and forced PWM mode, taking advantage from either lower power consumption or best dynamic performance. The device also includes soft-start control, thermal shutdown and current limit.
- Typical efficiency higher than 94%
- Automatic transition between step-down and boost mode
- Power save mode (PS) at light load
- 2.0MHz fixed switching frequency
- Adjustable switching frequency up to 2.4MHz (by external synchronous square signal)
- Device quiescent current less than 50µA
- Load disconnect during shutdown
- Shutdown function and soft-start
- <1µA Shutdown current
