PF1510: Power Management Integrated Circuit (PMIC) for Low Power Application Processors

Overview

The PF1510 is a Power Management Integrated Circuit (PMIC) designed specifically for use with i.MX processors on low-power portable, smart wearable and Internet-of-Things (IoT) applications.

It is also capable of providing full power solution to i.MX 7ULP, i.MX 6SL, 6UL, 6ULL and 6SX processors.

With three high-efficiency buck converters, three linear regulators, DDR reference and RTC supply, the PF1510 can provide power for a complete system, including application processors, memory, and system peripherals. The PF1510 is available in power efficient, space-saving 5x5mm QFN package.
