PMICs provide multi-channel operation

The NCP6924 and NCP6914 power management ICs (PMICs) are optimized for battery powered systems such as smartphones, tablets, digital cameras, GPS systems and other portable electronics. The NCP6924 integrates two 800-mA, 3-MHz step-down dc/dc converters and four LDO voltage regulators for 105-µA total quiescent current. The NCP6914 has the same parts except that it integrates a single 800-mA and features 72-µA quiescent current.

Both PMICs feature five and six voltage rails and are sized to supply power to mixed signal modules such as cameras, or to complement power distribution to an application processor under minimum supervision. Programming flexibility is offered through an I2 C interface that controls power up sequencing, enables and disables output power and controls individual active output discharges. The dc/dc converters’ output voltage can be programmed from 0.6 to 3.3–V in 12.5–mV steps and LDO regulators from 1.0 to 3.3–V in 50-mV steps. (Ea/10,000: NCP6924, $1.85; NCP6914, $1.35 — available now.)
