The BV8060/1 is a highly integrated power solution with a four-output SIQO buck converter, one LDO to generate five multi-channel output voltages with single inductors. The PMIC can achieve much smaller PCB area and lower BOM cost than traditional multi-channel PMIC which needs more inductors. The power supply is 5uA quiescent current at low power mode. The output voltages and power sequence of the voltage output rails can be adjusted by IIC interface or ENx/RSET interface based on application requirement. Its normal operating input voltage range is 2.7V to 5.5V.
Therefore, BV8060/1 is an optimized power solution for TWS and wearable systems. BV8060/1 is available in the CSP-16P 1.75mmx1.8mm package and QFN3x3-16L..
