General description

The PF1550 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 converter, three linear regulators, RTC supply, and battery

linear charger, the PF1550 can provide power for a complete battery-powered system,

including application processors, memory, and system peripherals.

1.1 Features and benefits
