NXP Semiconductors PF1510 PMICs

NXP Semiconductors PF1510 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 NXP PMICs provide a full power solution to i.MX 7ULP, i.MX 6SL, 6UL, 6ULL, and 6SX processors. The PF1510 PMICs in combination with three high-efficiency buck converters, three linear regulators, DDR reference, and RTC supply provide power for a complete system. These PMICs feature buck converters, LDO regulators, and an I2C interface. Typical applications include home automation, e-readers, smart mobiles, IoT, and embedded monitoring systems.
