NCP6951B Datasheet, PDF (1/35 Pages) ON Semiconductor – Camera PMIC with Flash LED Driver

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.
