PF1550

Power management integrated circuit (PMIC) for low power

application processors

Rev. 5 — 10 June 2019

Product data sheet

1 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

This section summarizes the PF1550 features:

• Input voltage range to PMIC VBUSIN pin via USB bus or AC adapter: 4.1 V to 6.0 V

• Buck converters:

– SW1, 1.0 A; 0.6 V to 1.3875 V in 12.5 mV steps, or 1.1 V to 3.3 V in variable steps

– SW2, 1.0 A; 0.6 V to 1.3875 V in 12.5 mV steps, or 1.1 V to 3.3 V in variable steps

– SW3, 1.0 A; 1.8 V to 3.3 V in 100 mV steps

– Soft start

– Quiescent current 1.0 μA in ULP mode with light load

– Peak efficiency > 90 %

– Dynamic voltage scaling on SW1 and SW2

– Modes: forced PWM quasi-fixed frequency mode, adaptive variable-frequency mode

– Programmable output voltage, current limit, and soft start

• LDO regulators

– LDO1, 0.75 V to 1.5 V/1.8 to 3.3 V, 300 mA with load switch mode

– LDO2, 1.8 V to 3.3 V, 400 mA

– LDO3, 0.75 V to 1.5 V/1.8 V to 3.3 V, 300 mA with load switch mode

– Quiescent current < 1.5 μA in Low-power mode

– Programmable output voltage

– Soft start and ramp

– Current limit protection

• Battery charger

– Supports single-cell Lithium Ion/Lithium Polymer batteries

– Linear charging (10 mA to 1500 mA input limit)

– Up to 6.5 V input operating range

– VSYS regulator can withstand transient and DC inputs from 0 V up to +22 V

– Programmable charge voltage (3.5 V to 4.44 V)

– Programmable charge current (100 mA to 1000 mA)

– Programmable charge termination current (5.0 mA to 50 mA)
