Automotive Power Management IC
PMIC for Automotive Camera
BD868xxMUF-C Series
General Description
Key Specifications
The PMIC BD868XXMUF-C series consists of primary
DCDC, dual secondary DCDC, secondary liner regulator
for CMOS sensor, and image sensing power supply.
This IC is optimal for camera module, which requires
small board with small package VQFN20FV3535.
This IC has the spread spectrum providing a lower noise
regulated outputs.
