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.
