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)
