5 Channel PMIC: 1 DCDC

Converter and 4 LDOs

The NCP6914 integrated circuits are part of the ON Semiconductor

mini power management IC family (PMIC). They are optimized to

supply battery powered portable application sub−systems such as

camera function and microprocessors. These devices integrate 1 high

efficiency 800 mA Step−down DC to DC converter with DVS

(Dynamic Voltage Scaling) and four low−dropout (LDO) voltage

regulators in a WLCSP20 1.77 x 2.06 mm package.
