STMICROELECTRONICS STBB3JCCR 芯片, 直流/直流转换器, 带WLED驱动器, 2A, FLIPCHIP-20
The 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 RDSon 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.
