Product details
Overview
MC34PF3000A7EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors with DDR3L memory, featuring four buck regulators (SW1A/B up to 2.75 A combined), six LDOs, RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5–0.9 V), and coin-cell charging. It powers full-system rails including CPU cores, memory, SD interfaces, and peripherals in industrial embedded designs.
For engineers reviewing the MC34PF3000A7EPR2 datasheet, MC34PF3000A7EPR2 pinout, MC34PF3000A7EPR2 application, or MC34PF3000A7EPR2 equivalent, key selection considerations include OTP-programmable startup sequence, dynamic voltage scaling (DVS) support for SW1A/SW1B/SW2/SW3, I²C-configurable regulator voltages, and industrial-grade temperature range (−40 °C to +105 °C) with wettable-flank 48-QFN packaging.
Technical Context
The MC34PF3000A7EPR2 implements a SMARTMOS-based PMIC architecture with configurable buck topology: SW1A (1.0 A) and SW1B (1.75 A) operate independently or combine into a single 2.75 A channel; SW2 delivers 1.25 A at 1.50–1.85 V or 2.50–3.30 V; SW3 supplies 1.5 A at 0.90–1.65 V. All buck regulators support PWM/PPM/APS modes, programmable soft-start timing, and DVS control via I²C.
It integrates seven regulated outputs: VCC_SD (1.8 V/3.3 V selectable), V33 (2.85–3.30 V, 350 mA), VLDO1–VLDO4 (0.8–3.3 V, 100–350 mA), VSNVS (3.0 V, 1.0 mA), and VREFDDR (0.5×SW3_OUT, 10 mA). Startup behavior is defined by one-time programmable (OTP) memory, eliminating external configuration components and enabling deterministic power-up sequencing for i.MX 6UL systems.
Key Specifications

Pinout & Package
MC34PF3000A7EPR2 uses a 48-pin 7.0 mm × 7.0 mm wettable-flank QFN package (NXP part number 98ASA00933D) with exposed thermal pad (EP) tied to ground for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Signals fault conditions (OCP, UVLO, thermal) to host processor; requires external pull-up |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after final regulator enable in startup sequence; configurable for fault-monitoring mode |
| PWRON | Power-on control input | Configurable as level- or edge-sensitive trigger; supports mechanical switch debounce (31.25–750 ms) |
| SD_VSEL | Digital select input | Switches VCC_SD output between 1.8 V/1.85 V (HIGH) and 2.85 V/3.30 V (LOW) for SD card interface compliance |
| SCL / SDA | I²C interface pins | Enable real-time reconfiguration of regulator voltages, sequencing, and operating modes post-power-up |
| VIN / VPWR | Main power inputs | VIN accepts ≤4.5 V directly; VPWR supports 3.7–5.5 V via external PFET front-end LDO |
| GNDREF1 / GNDREF2 / GNDREF | Ground references | Separate analog ground returns for buck regulators (SW1A/B, SW2/SW3) and core logic - critical for noise isolation |
| SW1ALX / SW1BLX / SW2LX / SW3LX | Switch node outputs | Connect to respective inductors; unused nodes must be left unconnected per datasheet guidance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A7ES | Automotive-grade variant (−40 °C to +105 °C), identical OTP programming option '7' for i.MX 6UL + DDR3L, but qualified to AEC-Q100 Grade 2 | Targeted for automotive infotainment and ADAS ECUs requiring automotive qualification | Select MC33PF3000A7ES only when AEC-Q100 compliance is mandatory; otherwise MC34PF3000A7EPR2 offers lower cost and same electrical functionality for industrial use |
| PF8100A7EPR2 | Newer NXP PMIC with higher integration: adds USB Type-C PD controller, enhanced thermal monitoring, and dual-phase SW1 (3.5 A), but lacks coin-cell charger and VSNVS switch | Designed for next-gen i.MX 8M Mini/Plus platforms with USB-C power delivery requirements | Choose PF8100A7EPR2 only if USB-C PD support and higher current capability are required; MC34PF3000A7EPR2 remains optimal for cost-sensitive i.MX 6UL DDR3L designs with RTC backup needs |
Compared with MC33PF3000A7ES, MC34PF3000A7EPR2 provides identical power tree configuration and OTP option '7' but targets industrial rather than automotive qualification-reducing cost without sacrificing thermal or electrical performance. Against PF8100A7EPR2, it trades newer features like USB-C PD for proven DDR3L support, coin-cell charging, and lower system-level BOM complexity.

FAQ
What is the OTP programming option encoded in MC34PF3000A7EPR2?
The "A7" suffix in MC34PF3000A7EPR2 indicates OTP programming option 7, which configures the PMIC for i.MX 6UL processors with DDR3L memory. This preset defines default startup sequence, regulator voltage setpoints (e.g., SW1A = 0.95 V for ARM core, SW3 = 1.35 V for DDR), and I²C address (0x08). The OTP is factory-programmed and cannot be modified in the field.
Does MC34PF3000A7EPR2 support dynamic voltage scaling (DVS) for all buck regulators?
Yes, MC34PF3000A7EPR2 supports DVS on SW1A, SW1B, SW2, and SW3 buck regulators via I²C-controlled voltage register writes. Each regulator's output can be adjusted in 25 mV steps with programmable ramp rates (2.0 μs or 4.0 μs per step), enabling real-time adaptation to CPU load changes while maintaining DDR3L interface compliance through synchronized VREFDDR tracking.
How does MC34PF3000A7EPR2 handle input voltages above 4.5 V?
MC34PF3000A7EPR2 accepts input voltages up to 5.5 V using the VPWR pin with an external P-channel MOSFET configured as a front-end LDO. The internal control circuitry regulates VPWR-derived rails to ≤4.5 V, protecting downstream buck and LDO stages. VIN pin usage is restricted to ≤4.5 V systems; mixing VIN and VPWR is not supported.
What is the function of the SD_VSEL pin on MC34PF3000A7EPR2?
The SD_VSEL pin on MC34PF3000A7EPR2 selects the output voltage range of the VCC_SD LDO: logic HIGH sets 1.80–1.85 V for high-speed SD card operation, while logic LOW sets 2.85–3.30 V for standard SDIO peripherals. The input buffer is powered by VDDIO, and defaults to HIGH if VDDIO is absent - ensuring safe fallback behavior during power sequencing.
Can MC34PF3000A7EPR2 power both DDR3L and LPDDR2 memory simultaneously?
No, MC34PF3000A7EPR2 is pre-configured for DDR3L memory via OTP option '7' and generates VREFDDR as 50% of SW3 output. While SW3 voltage is adjustable (0.90–1.65 V), the VREFDDR circuit is fixed-ratio and not compatible with LPDDR2's 0.6 V reference requirement. For LPDDR2 support, MC34PF3000A6EPR2 (OTP option '6') must be used instead.
