NCP6951B

Camera PMIC with Flash

LED Driver

The NCP6951B integrated circuit is part of the ON Semiconductor

mini power management IC family. It is optimized to supply battery

powered portable application sub−systems such as camera function,

microprocessors... etc. This device integrates one high efficiency

600 mA Step−down DCDC converter with DVS (Dynamic Voltage

Scaling), 5 low dropout (LDO) voltage regulators and a 1.5 A Flash

LED driver in WLCSP24 package.
