單電感多路輸出
The BV8001Q-QW is a highly integrated power solution with a 4-ouput SIMO buck converter, 1 LDO to generate five positive output voltages with only one inductors.
The PMIC can achieve much smaller PCB area and lower BOM cost than traditional multi-channel PMIC which needs more inductors. The overall power conversion efficiency of BV8001 is also comparable with that of a traditional PMIC integrating several dc/dc converters and LDOs. The output voltages and power sequence of the voltage output rails can be adjusted by II2 interface and built-in NVM based on application requirement.
BV8001Q-QW is an AEC-Q100 grade 1 qualified solution for automotive camera module and is available in the QFN-24L 4mmx4mm package.
