The BV8003QW is a highly integrated power solution with a 4-ouput SIMO buck converter, 2 LDOs and a high-speed step-down converter to generate seven positive output voltages with only two 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 BV8003 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 IIC interface and be preset by built-in NVM based on application requirement. Its normal operating input voltage range is 4.5V to 17V. Therefore, BV8003 is an optimized power solution for Automotive Camera Module.
BV8003QW is available in the Wettable QFN-28L 4mmx4mm package.
