NCP6924AFCET1G ON Semiconductor

NCP6924 6 Channel PMIC with 2 DCDC Converters and 4 LDOs The NCP6924 integrated circuit is part of the ON Semiconductor mini power management IC family (PMIC). It is optimized to supply battery powered portable application subsystems such as camera www.onsemi.com function, microprocessors. This device integrates two high efficiency up to 1.0 A stepdown DCDC converters with Dynamic Voltage Scale MARKING (DVS) and 4 low dropout (LDO) voltage regulators in a WLCSP30 DIAGRAM* 2.46 x 2.06 mm package.
