Product details
Overview
MC34PF3001A2EP from NXP Semiconductors is a fixed-configuration power management IC (PMIC) designed exclusively for i.MX 7 processors with LPDDR3 memory. It integrates three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs including VCC_SD (100 mA, dual-voltage SD card support), and an always-on RTC supply (VSNVS: 3.0 V, 1.0 mA), delivering full power sequencing for multimedia application processors in industrial edge devices.
For engineers reviewing the MC34PF3001A2EP datasheet, MC34PF3001A2EP pinout, MC34PF3001A2EP application, or MC34PF3001A2EP equivalent, this page provides verified regulator output voltages, OTP-programmed startup sequence (SW1=1.10 V, SW2=1.8 V, SW3=1.2 V), I²C address (0x08), thermal design guidance, and confirmed industrial temperature range (−40 °C to +105 °C).
Technical Context
The MC34PF3001A2EP implements a fixed OTP-based power tree with hardwired sequencing logic: SW1 powers the ARM Cortex-A7 core (VDD_ARM), SW2 supplies I/O domains (VDDA_1P8, NVCC_DRAM_CKE), and SW3 delivers DDR PHY voltage (NVCC_DRAM_CKE). Its internal 32 kHz trimmed clock governs startup timing, while a factory-trimmed 16 MHz RC oscillator sets switching frequency at 2.0 MHz across all bucks.
Regulator control combines direct logic interface (PWRON, RESETBMCU, INTB, SD_VSEL) with I²C programmability for dynamic voltage scaling and fault monitoring. The device supports optional front-end VPWR LDO operation via external P-MOSFET for input voltages up to 5.5 V, while maintaining VIN-referenced operation below 4.5 V.

Pinout & Package
MC34PF3001A2EP uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, code 98ASA00933D) with exposed thermal pad (EP) tied to ground for enhanced thermal dissipation. Pin functions are validated per NXP PF3001 datasheet Rev. 5.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Asserts low on fault (overvoltage, thermal, short-circuit); requires external pull-up |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after final regulator enables; signals system ready to processor |
| SD_VSEL | Digital input control | Selects VCC_SD output: LOW = 2.85–3.3 V, HIGH = 1.80–1.85 V for SD card compatibility |
| SW1LX, SW2LX, SW3LX | Buck switch node outputs | Connect directly to respective inductors; high di/dt paths require tight layout |
| VIN, VPWR | Main and auxiliary inputs | VIN used for ≤4.5 V systems; VPWR enables external LDO for 4.5–5.5 V inputs |
| GNDREF1/GNDREF2/GNDREF | Separate analog ground references | Isolate buck feedback and core reference grounds from noisy power return paths |
| LICELL | Coin cell interface | Charges backup battery and supplies VSNVS during main power loss |
| EP | Exposed thermal pad | Must be soldered to PCB ground plane with ≥4 thermal vias for thermal compliance |
Key Features

FAQ
What is the default I²C address for MC34PF3001A2EP?
The default I²C slave address for MC34PF3001A2EP is 0x08. This address is factory-programmed in OTP and remains fixed across all A2 variants. While the device supports limited runtime register modification via I²C, the base address cannot be changed without hardware redesign or alternative part selection.
Does MC34PF3001A2EP support dynamic voltage scaling (DVS)?
Yes, MC34PF3001A2EP supports dynamic voltage scaling on SW1, SW2, and SW3 buck regulators via I²C register writes to SWxVOLT[4:0]. DVS ramp rate is fixed at 12.5 mV/µs per OTP configuration A2, enabling controlled core voltage transitions during processor frequency changes without external control circuitry.
What is the purpose of the SD_VSEL pin on MC34PF3001A2EP?
The SD_VSEL pin on MC34PF3001A2EP selects the output voltage range of the VCC_SD LDO: logic LOW configures 2.85–3.3 V for standard SD cards, while logic HIGH selects 1.80–1.85 V for UHS-I SD interfaces. This hardware-selectable feature eliminates need for external voltage translators in dual-mode SD host designs.
Can MC34PF3001A2EP operate with a 5.0 V input supply?
Yes, MC34PF3001A2EP supports 5.0 V input via the VPWR pin when used with an external P-channel MOSFET (e.g., FDMA908PZ) configured as a front-end LDO. In this mode, VIN is derived from VPWR regulation, limiting internal regulator input to ≤4.5 V. Direct 5.0 V connection to VIN is not permitted and may damage the device.
What is the function of the VSNVS output on MC34PF3001A2EP?
The VSNVS output on MC34PF3001A2EP provides a dedicated 3.0 V, 1.0 mA always-on supply for the Secure Non-Volatile Storage (SNVS) and Real-Time Clock (RTC) domains of i.MX 7 processors. It remains active during system shutdown and supports coin cell backup via the LICELL pin for continuous timekeeping and tamper-resilient security state retention.
