NXP Semiconductors PF1550 PMICs
NXP Semiconductors PF1550 Power Management Integrated Circuits (PMICs) are designed for use with i.MX processors on low-power portable, smart wearable, and Internet of Things (IoT) applications. These PMICs provide a full power solution to i.MX 7ULP, i.MX 6SL, 6UL, 6ULL, and 6SX processors. NXP PF1550 PMICs, in combination with three high-efficiency buck converters, three linear regulators, an RTC supply, and a battery linear charger, provide power for a complete battery-powered system. These PMICs feature 3 user-programmable LDO regulators, I2C interface, a DDR termination reference voltage, and a 1A linear Li-Ion battery charger. Typical applications include home automation, e-readers, smart mobiles, IoT, wireless game controllers, and embedded monitoring systems.
