Power Management IC for DSC/DVCs - BD8355MWV

D8355MWV is a system switching regulator for Li 2 cell composed of 6 step-down synchronous rectification channels and 1 step-up Di rectification channel for LED application. Using a charge-pump system for high side FET driver and including power MOSFET reduce the number of peripheral devices and realize high efficiency.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
