Product details
Overview
MC34PF3001A1EPR2 from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) engineered specifically for i.MX 7 processors with DDR3L memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs, and an always-on VSNVS rail (3.0 V, 1.0 mA). It supports dynamic voltage scaling, I²C programmability, and coin-cell backup for RTC functionality in embedded multimedia systems.
For engineers reviewing the MC34PF3001A1EPR2 datasheet, MC34PF3001A1EPR2 pinout, MC34PF3001A1EPR2 application, or MC34PF3001A1EPR2 equivalent, this page provides verified regulator output voltages, OTP-configured startup sequence (SW1_SEQ=1, SW2_SEQ=2, SW3_SEQ=5), thermal-safe QFN-48 wettable flank package details, and validated alternative PMICs for i.MX 6/7 system designs.
Technical Context
The MC34PF3001A1EPR2 implements a fixed OTP-based power tree with trimmed 32 kHz and 16 MHz clocks governing startup timing and switching frequency (2.0 MHz for all bucks). Its control logic integrates PWRON-triggered state transitions, open-drain RESETBMCU (deasserted 2.0 ms after final regulator enable), and INTB fault signaling with maskable interrupts.
Regulator operation includes APS (pulse-skipping) as default mode, with programmable PWM/PPM/PFM selection per buck; SW1 supports 0.7–1.425 V or fixed 1.8/3.3 V outputs; SW2 offers dual ranges (1.5–1.85 V or 2.5–3.3 V); SW3 covers 0.9–1.65 V; VCC_SD toggles between 1.80–1.85 V and 2.85–3.3 V via SD_VSEL pin.

FAQ
What is the default I²C address for MC34PF3001A1EPR2?
The default I²C address for MC34PF3001A1EPR2 is 0x08, as specified in Table 4 of the PF3001 datasheet Rev. 5.1. This address is factory-trimmed and cannot be altered by OTP programming. All register reads and writes to MC34PF3001A1EPR2 must use this base address, with optional 7-bit or 8-bit format depending on controller implementation. The address remains consistent across all A1–A7 variants.
Does MC34PF3001A1EPR2 support dynamic voltage scaling for all buck regulators?
MC34PF3001A1EPR2 supports dynamic voltage scaling (DVS) only for SW1 and SW2 buck regulators via I²C-controlled DACs; SW3 voltage is programmable but lacks DVS ramp-rate control. The DVS speed for SW1 is fixed at 12.5 mV/µs per Table 4, enabling precise core voltage transitions during i.MX 7 performance state changes. SW3 operates with static voltage configuration post-startup.
What is the purpose of the SD_VSEL pin on MC34PF3001A1EPR2?
The SD_VSEL pin on MC34PF3001A1EPR2 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 SDIO interfaces. This pin is powered by VDDIO and defaults to high if VDDIO is absent, ensuring safe low-voltage operation during power-up sequences involving MC34PF3001A1EPR2.
Can MC34PF3001A1EPR2 operate with a 5.0 V input supply?
Yes, MC34PF3001A1EPR2 can operate with a 5.0 V input using the VPWR pin and an external P-channel MOSFET (e.g., FDMA908PZ), as described in Section 8.3.5. When VPWR > 4.5 V, the internal LDO control block activates LDOG to drive the PFET gate, regulating VIN to ≤4.5 V. Direct connection to VIN is only valid for inputs ≤4.5 V; exceeding this without VPWR configuration risks overvoltage damage to MC34PF3001A1EPR2.
What is the function of the RESETBMCU pin on MC34PF3001A1EPR2?
The RESETBMCU pin on MC34PF3001A1EPR2 is an open-drain, active-low output that deasserts 2.0 ms after the last regulator in the OTP-defined startup sequence (V33 for A1 variant) reaches regulation. It signals the i.MX 7 processor that all critical power rails are stable and ready, releasing it from power-on reset. RESETBMCU is timer-based-not rail-monitored-and asserts only during turn-off events or fault-induced shutdowns of MC34PF3001A1EPR2.
