Product details
Overview
MC34PF3000A1EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered exclusively for i.MX 7 processors with DDR3L memory, integrating four buck regulators (SW1A/B up to 2.75 A combined), six LDOs, RTC supply (VSNVS, 3.0 V), coin-cell charger, and DDR reference (VREFDDR, 0.5×SW3_OUT). It delivers full-system power for application processors, memory, and peripherals in industrial edge devices.
For engineers reviewing the MC34PF3000A1EPR2 datasheet, MC34PF3000A1EPR2 pinout, MC34PF3000A1EPR2 application, or MC34PF3000A1EPR2 equivalent, key selection criteria include OTP-programmable startup sequence, I²C-configurable dynamic voltage scaling across SW1A/SW1B/SW2/SW3, VPWR front-end LDO support for 3.7–5.5 V input, and wettable-flank 48-QFN package compatibility with i.MX 7 DDR3L power trees.
Technical Context
The MC34PF3000A1EPR2 implements a SMARTMOS-based multi-rail architecture with configurable buck topology: SW1A (1.0 A) and SW1B (1.75 A) operate independently or combine into a single 2.75 A phase-interleaved regulator. SW2 (1.25 A) supports dual output ranges (1.50–1.85 V or 2.50–3.30 V), while SW3 (1.5 A) supplies core voltages from 0.90 V to 1.65 V with programmable soft-start ramp rate (25 mV/2 µs or 4 µs).
Its control logic integrates OTP-programmed startup sequencing (15-slot timing with 0.5/2.0 ms resolution), I²C address configuration (0x08–0x0F), PWRON edge/level sensitivity, and RESETBMCU fault-mode assertion (1.8 ms fault hold time). The VREFDDR rail derives from SW3 output via internal 0.5× scaling, enabling precise DDR3L termination without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 3.7 V to 5.5 V (VPWR input) or 2.8 V to 4.5 V (VIN input); enables direct integration with 5 V systems or battery-backed industrial rails |
| SW1A/SW1B combined output | 2.75 A at 0.7–1.425 V; supports i.MX 7 ARM Cortex-A7 core voltage scaling with phase interleaving to reduce ripple |
| VREFDDR output | 0.5 × SW3_OUT (0.45–0.825 V); provides accurate DDR3L reference without external resistor divider or op-amp |
| VSNVS output | 3.0 V / 1.0 mA; powers i.MX 7 SNVS domain and RTC during deep sleep, backed by coin cell or VIN |
| I²C address range | 0x08–0x0F (OTP-programmable LSBs); avoids bus conflicts in multi-PMIC designs without hardware pin strapping |
| Startup sequence slots | 15 programmable positions (0.5/2.0 ms step); allows precise timing alignment between processor core, DDR, and peripheral rails |
| Package | 48-pin QFN, 7.0 mm × 7.0 mm, wettable flank; supports automated optical inspection (AOI) and high thermal dissipation in compact industrial PCBs |
Pinout & Package
MC34PF3000A1EPR2 uses the 48-pin 7.0 mm × 7.0 mm wettable-flank QFN package (98ASA00933D), optimized for thermal performance and solder-joint reliability in industrial temperature range (−40 °C to +105 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB (Pin 1) | Open-drain interrupt output | Signals overcurrent, thermal fault, or regulator failure to host processor; requires external pull-up to VDDIO |
| SW1ALX (Pin 8) / SW1BLX (Pin 9) | Switch node outputs | Connect to SW1A/SW1B inductors; tied together when operating in combined 2.75 A mode |
| VREFDDR (Pin 25) | DDR memory reference output | Delivers 0.5× scaled SW3 voltage (0.45–0.825 V) directly to DDR3L VTT; bypassed with 1.0 μF capacitor to GND |
| VSNVS (Pin 34) | Always-on RTC supply | Provides 3.0 V standby power to i.MX 7 Secure Non-Volatile Storage domain; backed by coin cell via LICELL pin |
| PWRON (Pin 48) | Power-on control input | Configurable as level- or edge-sensitive trigger; debounced (31.25–750 ms) for mechanical switch interfacing |
| EP (Exposed Pad) | Thermal ground plane | Must be connected to inner/external GND planes via multiple vias for thermal dissipation and low-impedance return path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3000A7EPR2 | OTP programmed for i.MX 6UL with DDR3L; different startup sequence and SW2 voltage range (1.5–1.85 V only) | Targeted at i.MX 6UL-based designs, not i.MX 7; incompatible DDR3L timing parameters and core voltage mapping | Select only if migrating from i.MX 6UL to i.MX 7 requires minimal hardware change but accepts firmware revalidation |
| MPQ4436AGL-AEC1-P | Automotive-grade 3.5 A buck converter (no integrated LDOs, OTP, or DDR reference); requires external sequencing and VREF generation | Suitable for standalone core supply in AEC-Q100 systems; lacks i.MX-specific features like SD_VSEL or VREFDDR | Choose when designing custom PMIC solution with discrete regulators and full control over sequencing, not drop-in replacement |
Compared with MC34PF3000A1EPR2, MC34PF3000A7EPR2 shares identical silicon and package but delivers incompatible OTP configuration for i.MX 6UL, while MPQ4436AGL-AEC1-P offers higher current density but demands external circuitry for DDR reference and multi-rail coordination-increasing BOM cost and layout complexity.

FAQ
What is the operating temperature range for MC34PF3000A1EPR2?
MC34PF3000A1EPR2 is rated for −40 °C to +105 °C, qualifying it for industrial applications including DIN-rail gateways and medical equipment. This range aligns with the "Industrial" designation in Table 1 of the datasheet and is enabled by its 48-QFN wettable-flank package and SMARTMOS process optimization. The device maintains full regulation and OTP functionality across this span without derating.
How does MC34PF3000A1EPR2 support DDR3L memory interfaces?
MC34PF3000A1EPR2 supports DDR3L through two dedicated features: VREFDDR output (0.5× SW3_OUT, 0.45–0.825 V) and SW2 regulator configured for 1.50–1.85 V operation. VREFDDR eliminates external resistor dividers, while SW2's voltage range matches DDR3L VDDQ specifications. Both rails are OTP-programmed to sequence after SW3, ensuring stable core voltage before memory initialization.
Can MC34PF3000A1EPR2 be used with i.MX 6UL processors?
No-MC34PF3000A1EPR2 is OTP-programmed specifically for i.MX 7 with DDR3L (programming option "1" per Table 1). Using it with i.MX 6UL would result in incorrect startup sequencing, mismatched SW2 voltage range, and improper DDR3L reference generation. For i.MX 6UL, MC34PF3000A6EPR2 (option "6") or MC34PF3000A7EPR2 (option "7") are required.
What input voltage configurations does MC34PF3000A1EPR2 support?
MC34PF3000A1EPR2 supports two input configurations: VIN (2.8–4.5 V) for direct connection to 3.3 V or 3.7 V battery systems, and VPWR (3.7–5.5 V) for 5 V rail operation using an external P-MOSFET controlled by LDOG. The VPWR path includes overvoltage protection and enables use in industrial 5 V systems without violating internal 4.5 V regulator limits.
Does MC34PF3000A1EPR2 include battery backup capability?
Yes-MC34PF3000A1EPR2 integrates a coin-cell charger and VSNVS regulator (3.0 V / 1.0 mA) that maintains RTC and SNVS domain power during main supply loss. The LICELL pin accepts 1.0–3.0 V coin cells (e.g., CR1220), with automatic switchover and trickle-charge control. This ensures timekeeping and secure state retention in battery-backed industrial and medical devices.
