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
