Product details
Overview
MC34PF3000A0EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered exclusively for i.MX 6UL application processors with DDR3 memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs including VCC_SD (100 mA, dual-voltage SD card support), and integrated DDR reference (VREFDDR: 0.5×SW3_OUT, 10 mA). It powers complete embedded systems in industrial control and home automation gateways.
For engineers reviewing the MC34PF3000A0EPR2 datasheet, MC34PF3000A0EPR2 pinout, MC34PF3000A0EPR2 application, or MC34PF3000A0EPR2 equivalent, key selection criteria include OTP-programmable startup sequencing, dynamic voltage scaling across core rails, I²C-configurable regulator voltages, and support for VPWR front-end LDO operation up to 5.5 V input.
Technical Context
The MC34PF3000A0EPR2 implements a multi-rail power architecture with configurable SW1A/SW1B pairing (independent or combined 2.75 A), programmable PWM/PSM switching modes, and hardware-managed power states (Off, Sleep/LPSR, Standby) controlled via PWRON, STANDBY, and RESETBMCU signals. Its OTP memory stores startup sequence timing, voltage setpoints, and I²C address (0x08–0x0F).
Regulator control integrates analog feedback loops (SWxFB, SWxIN, SWxLX pins) with digital supervision: INTB provides open-drain fault reporting, while VSNVS supplies 3.0 V @ 1.0 mA to SNVS domain and supports coin-cell backup. The VREFDDR rail derives from SW3 output with 0.5× scaling for DDR3L compliance.

Pinout & Package
MC34PF3000A0EPR2 uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, 98ASA00933D), rated for –40 °C to +105 °C industrial operation. Exposed thermal pad (EP) must be connected to ground planes via multiple vias for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

FAQ
What is the operating temperature range for MC34PF3000A0EPR2?
MC34PF3000A0EPR2 is rated for –40 °C to +105 °C industrial operation, validated for continuous use in enclosed enclosures with airflow constraints. This range supports deployment in factory-floor controllers and outdoor home automation hubs without derating. The device uses SMARTMOS technology to maintain regulation stability across the full span, with thermal shutdown protection activating above +125 °C junction temperature.
How does MC34PF3000A0EPR2 support DDR3L memory voltage referencing?
MC34PF3000A0EPR2 generates VREFDDR as 0.5 × SW3_OUT, providing a precision DDR3L reference (0.45–0.825 V) directly scaled from the SW3 buck regulator output. This eliminates external resistor dividers and ensures tight tracking between VREFDDR and DDR3L VDDQ, critical for signal integrity in high-speed memory interfaces used with i.MX 6UL processors.
Can MC34PF3000A0EPR2 operate with input voltages above 4.5 V?
Yes-MC34PF3000A0EPR2 supports up to 5.5 V input via the VPWR pin when paired with an external P-channel MOSFET configured as a front-end LDO. This configuration clamps internal regulator inputs to ≤4.5 V, enabling compatibility with 5 V USB-powered or 5.5 V industrial power rails while maintaining safe operation of the internal SMARTMOS circuitry.
What is the role of the SD_VSEL pin on MC34PF3000A0EPR2?
The SD_VSEL pin on MC34PF3000A0EPR2 selects the output voltage range of the VCC_SD LDO: logic low configures 2.85–3.30 V for standard SD cards, while logic high sets 1.80–1.85 V for UHS-I SDIO interfaces. This dual-voltage capability allows a single MC34PF3000A0EPR2 design to support both legacy and high-speed SD card implementations without hardware changes.
How is the startup sequence programmed in MC34PF3000A0EPR2?
The startup sequence in MC34PF3000A0EPR2 is stored in one-time-programmable (OTP) memory and defines the enable order and timing delays (0.5 ms or 2.0 ms steps) for all regulators. Each regulator is assigned a slot (1–15), and RESETBMCU deasserts 2.0 ms after the last enabled rail-ensuring i.MX 6UL core and memory supplies stabilize before processor release from reset.
