NXP Semiconductors KITPF1550FRDMPGM

Overview

KITPF1550FRDMPGM from NXP Semiconductors is a preprogrammed evaluation kit for the PF1550 power management integrated circuit (PMIC), designed to support rapid development of low-power i.MX-based portable and IoT systems. It integrates three 1.0 A buck converters, three LDOs, RTC supply, DDR reference voltage, and a programmable linear battery charger - enabling full power delivery for application processors, memory, and peripherals in wearable and embedded applications.

For engineers reviewing the KITPF1550FRDMPGM datasheet, KITPF1550FRDMPGM pinout, KITPF1550FRDMPGM application, or KITPF1550FRDMPGM equivalent, this kit provides validated hardware, reference schematics, firmware examples, and I²C-configurable power sequencing - critical for validating PMIC integration with i.MX 6UL/6ULL/7ULP processors before production design.

Technical Context

The KITPF1550FRDMPGM implements the PF1550 PMIC in a 40-pin QFN 5.0 mm × 5.0 mm package with exposed thermal pad, supporting industrial temperature range (−40 °C to 105 °C) and JEITA-compliant battery thermal monitoring. Its architecture includes dynamic voltage scaling on SW1/SW2, OTP-programmable startup/power-down sequences, and integrated 50 mΩ battery isolation FET for no-battery operation.

It delivers system-level power control via I²C interface (SCL/SDA), supports USB PHY LDO (60 mA), coin cell charging, and features dedicated pins for watchdog (WDI), reset (RESETBMCU), push-button (ONKEY), and interrupt signaling (INTB). The board enables validation of VSYS transient response, battery supplement mode, and load-switch-capable LDO1/LDO3 operation.

FAQ

What is the primary function of the KITPF1550FRDMPGM evaluation kit?

The KITPF1550FRDMPGM evaluation kit provides a fully assembled and tested hardware platform to evaluate the PF1550 PMIC's power delivery capabilities for i.MX application processors. It enables engineers to validate buck converter regulation, LDO sequencing, battery charging behavior, I²C configuration, and thermal performance - accelerating bring-up of low-power portable designs using the KITPF1550FRDMPGM and its underlying PF1550 IC.

Which i.MX processors does the KITPF1550FRDMPGM support out of the box?

The KITPF1550FRDMPGM is preprogrammed with OTP configuration A2, optimized for the i.MX 7ULP processor with LPDDR3 memory. It also supports i.MX 6UL, 6ULL, and 6SX variants through reconfiguration via I²C registers or OTP reprogramming - but default operation and reference schematics are validated for i.MX 7ULP + LPDDR3 use cases per the KITPF1550FRDMPGM documentation.

Does the KITPF1550FRDMPGM include battery charging circuitry and protection features?

Yes, the KITPF1550FRDMPGM implements the full PF1550 battery charger functionality: linear charging up to 1000 mA, programmable 3.5–4.44 V charge voltage, JEITA-compliant thermistor monitoring, battery overcurrent protection (2.0–4.0 A threshold), and battery supplement mode. It includes all necessary external components - including current-sense resistors, thermistor biasing, and CHGB LED driver - enabling immediate validation of charging behavior with single-cell Li-ion batteries.

Can the KITPF1550FRDMPGM be used to verify power sequencing and low-power modes?

Yes, the KITPF1550FRDMPGM supports full verification of user-programmable power sequencing (startup, sleep, standby, off) via OTP or real-time I²C commands. It demonstrates transitions between REGS_DISABLE, Low-power, and Sleep modes - including quiescent current <1.5 μA for LDOs and 1.0 μA for bucks in ULP mode - using onboard test points and firmware examples that exercise ONKEY, PWRON, and STANDBY control signals.

Is the KITPF1550FRDMPGM compatible with standard development tools and software?

Yes, the KITPF1550FRDMPGM is supported by NXP's MCUXpresso SDK, Power Quad configuration tools, and Linux kernel drivers for i.MX platforms. It interfaces via standard 0.1″ headers for logic analyzers and debug probes, and includes jumpers for I²C pull-up selection, voltage monitoring, and interrupt routing - ensuring compatibility with common bench equipment and NXP's official software ecosystem for the KITPF1550FRDMPGM.
