PF1510 Power management integrated circuit (PMIC) for low power application processors Rev. 4 5 March 2021 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 A 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 A 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 chargerNXP Semiconductors PF1510 Power management integrated circuit (PMIC) for low power application processors DDR memory reference voltage, VREFDDR, 0.5 to 0.9 V, 10 mA OTP (One time programmable) memory for device configuration User programmable start-up sequence, timing, soft-start and power-down sequence Programmable regulator output voltages 2 I C interface User programmable Standby, Sleep/Low-power, and Off (REGS DISABLE) modes Ambient temperature range 40 C to 105 C 1.2 Applications Low-power IoT applications Wireless game controllers Embedded monitoring systems Home automation POS E-Reader Smart mobile/wearable devices PF1510 All information provided in this document is subject to legal disclaimers.
