Product details
Overview
MC34PF3001A3EPR2 from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 6 SoloX processors with DDR3L memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs including VCC_SD and V33, and integrated RTC backup with coin cell charging. It operates from 2.8–4.5 V input and supports dynamic voltage scaling for ARM core and I/O rails in industrial embedded systems.
For engineers reviewing the MC34PF3001A3EPR2 datasheet, MC34PF3001A3EPR2 pinout, MC34PF3001A3EPR2 application, or MC34PF3001A3EPR2 equivalent, this page provides verified regulator output voltages, OTP-configured startup sequence (SW1=1.375 V, SW2=3.3 V, SW3=1.35 V), I²C programmability, thermal protection, and industrial-grade temperature range (−40 °C to +105 °C) for reliable system power design.
Technical Context
The MC34PF3001A3EPR2 implements a fixed OTP-based power tree with sequenced startup (SW1 SEQ=2, SW2 SEQ=4, SW3 SEQ=3, V33 SEQ=1) and hardwired DVS ramp rate (6.25 mV/μs), eliminating external configuration components. Its triple-buck architecture supplies core (VCOREDIG), memory (NVCC_DRAM_CKE), and I/O (VDDA_1P8) domains while sharing a trimmed 16 MHz clock for switching frequency stability (2.0 MHz nominal).
It integrates an always-on VSNVS rail (3.0 V, 1.0 mA) with coin cell charger and bias control, plus VPWR front-end LDO support via external P-MOSFET for >4.5 V inputs. All regulators reference a single internal bandgap, with VCOREREF (220 nF bypass), VCOREDIG (1.28 V in off mode), and GNDREF isolation critical for noise-sensitive analog core operation.

Pinout & Package
MC34PF3001A3EPR2 uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, 98ASA00933D), with exposed thermal pad (EP) tied to ground plane for thermal dissipation. Pin functions are defined per NXP PF3001 Rev. 5.1 datasheet Section 7.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN / SW1LX (pins 7,8,9,10) | Buck 1 power path | SW1IN accepts input; SW1LX connects to inductor switch node - requires 4.7 μF + 0.1 μF local decoupling |
| SW2FB / SW2LX (pins 17,19) | Buck 2 feedback & switching | SW2FB enables precision regulation of 3.3 V DDR3L I/O rail; SW2LX drives external inductor |

FAQ
What is the default I²C address for MC34PF3001A3EPR2?
The MC34PF3001A3EPR2 uses a fixed default I²C address of 0x08, consistent across all PF3001 variants. This address is hardwired and cannot be changed via pins or OTP; it allows direct integration into multi-PMIC systems without address conflict, provided pull-up resistors are correctly sized (4.7 kΩ to VDDIO).
Does MC34PF3001A3EPR2 support dynamic voltage scaling (DVS) for the core rail?
Yes, MC34PF3001A3EPR2 supports DVS on SW1 (core rail) with a ramp rate of 6.25 mV/μs per OTP A3 configuration. This enables controlled voltage transitions during processor frequency scaling, reducing power consumption while maintaining stability - critical for thermal management in fanless industrial enclosures.
How does the SD_VSEL pin affect VCC_SD output voltage in MC34PF3001A3EPR2?
In MC34PF3001A3EPR2, the SD_VSEL pin selects between two VCC_SD output ranges: logic HIGH sets 1.80–1.85 V for 1.8 V SD cards, while logic LOW sets 2.85–3.30 V for 3.3 V SD cards. The selection is hardware-based and active immediately at power-up, independent of I²C configuration.
What is the purpose of the VPWR pin on MC34PF3001A3EPR2?
The VPWR pin on MC34PF3001A3EPR2 enables optional front-end LDO operation for input voltages above 4.5 V (up to 5.5 V). When used, an external P-MOSFET (e.g., FDMA908PZ) is required; VPWR connects to the main supply, and VIN is driven by the LDO output - protecting internal regulators from overvoltage stress.
Is MC34PF3001A3EPR2 compatible with i.MX 7 processors?
No, MC34PF3001A3EPR2 is specifically OTP-programmed for i.MX 6 SoloX with DDR3L (configuration A3). While the PF3001 family supports i.MX 7, A3's startup sequence, core voltage (1.375 V), and DDR I/O settings are mismatched for i.MX 7 requirements - use MC32PF3001A1ES/A2ES instead for i.MX 7 designs.
