PF1510

Power management integrated circuit (PMIC) for low power

application processors

Rev. 3 — 7 April 2020

Product data sheet

1 General description

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.

1.1 Features and benefits

This section summarizes the PF1510 features:

• Input voltage VIN from 5V bus, USB, or AC adapter (4.1 V to 6.0 V)

– Linear front-end input LDO (1500 mA input limit)

– Up to 6.5 V input operating range

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

– Internal digital 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 to 1.5 V/1.8 to 3.3 V, 300 mA with load switch mode

– LDO2, 1.8 to 3.3 V, 400 mA

– LDO3, 0.75 to 1.5 V/1.8 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

– USB_PHY low dropout linear regulator

– LDO2P7 always on regulator output

• LDO/switch supply

– RTC supply VSNVS 3.0 V, 2.0 mA

– Coin cell charger
