Product details
Overview
MC34PF3000A8EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered 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 V33 (350 mA) and VCC_SD (100 mA), RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5×VDDR), and coin-cell charging - enabling full-system power for industrial embedded gateways and HMI controllers.
For engineers reviewing the MC34PF3000A8EPR2 datasheet, MC34PF3000A8EPR2 pinout, MC34PF3000A8EPR2 application, or MC34PF3000A8EPR2 equivalent, key selection factors include its -40 °C to 105 °C industrial temperature rating, OTP-programmable startup sequence, I²C-configurable dynamic voltage scaling, and 48-pin QFN wettable flank package optimized for thermal reliability in space-constrained designs.
Technical Context
The MC34PF3000A8EPR2 integrates SMARTMOS technology to support dual-mode operation of SW1A/SW1B - either as independent 1.0 A/1.75 A buck regulators or combined into a single 2.75 A channel - with programmable PWM/PPM/APS modes, soft-start sequencing, and 25 mV/2–4 μs DVS ramp control. Its OTP memory stores startup voltages, timing, and I²C address (0x08–0x0F), eliminating external configuration components.
It features dedicated analog blocks: VREFDDR (0.5×SW3_OUT, 10 mA) for DDR3 termination, VSNVS (3.0 V, 1.0 mA) for secure real-time clock backup, and VPWR front-end LDO support via external P-MOSFET for input voltages up to 5.5 V. Control logic includes level- or edge-triggered PWRON, active-high/low STANDBY, and open-drain INTB/RESETBMCU with fault interrupt masking.

Pinout & Package
MC34PF3000A8EPR2 uses a 48-pin QFN package (98ASA00933D), 7.0 mm × 7.0 mm, wettable flank (WF-type), with exposed thermal pad (EP) tied to ground for enhanced thermal dissipation in high-power industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB (Pin 1) | Open-drain interrupt output | Asserts low on fault (OCP, UVLO, thermal); requires external pull-up for processor alert signaling |
| SW1ALX (Pin 8) & SW1BLX (Pin 9) | Switch node outputs | Connect to respective inductors in independent mode; shorted together when SW1A/B operate as single 2.75 A channel |
| VCC_SD (Pin 33) | Dual-range SD card LDO | Outputs 1.80–1.85 V (SD_VSEL=1) or 2.85–3.30 V (SD_VSEL=0); supports high-speed SDIO interfaces |
| VREFDDR (Pin 25) | DDR memory reference output | Delivers 0.5×SW3_OUT (0.5–0.9 V) with 10 mA drive; tracks core voltage for DDR3L termination accuracy |
| EP (Exposed Pad) | Thermal & ground return | Must be soldered to internal/external ground planes via multiple vias; critical for thermal performance and noise reduction |
Key Features
| Feature | Design Value |
|---|---|
| Configurable SW1A/SW1B topology | Supports independent 1.0 A / 1.75 A operation or combined 2.75 A mode - adapts to i.MX 6UL core power demand without hardware change |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A7ES | Same silicon, -40 °C to 105 °C automotive grade; OTP pre-programmed for i.MX 6UL with DDR3L; no R2 tape-and-reel suffix | Qualified to AEC-Q100 Grade 2; intended for automotive infotainment, not industrial | Select MC33PF3000A7ES only if AEC-Q100 compliance and automotive qualification are required; MC34PF3000A8EPR2 is preferred for industrial use cases. |
| MPQ4333GQ-AEC1 | Monolithic 3-channel buck converter (3A/2A/2A); no integrated LDOs, OTP, VREFDDR, or coin-cell charging | Lacks PMIC-level integration; requires external LDOs, sequencer, and RTC backup circuitry | Choose MPQ4333GQ-AEC1 only for cost-sensitive, non-i.MX designs where full PMIC functionality is unnecessary and board space permits discrete support components. |
Compared with MC33PF3000A7ES, MC34PF3000A8EPR2 offers identical electrical performance but targets industrial rather than automotive qualification, while MPQ4333GQ-AEC1 demands significant external component additions to match even basic PF3000 functionality - making MC34PF3000A8EPR2 the optimal choice for i.MX 6UL-based industrial systems requiring integrated, OTP-configured power.

FAQ
What is the operating temperature range for MC34PF3000A8EPR2?
MC34PF3000A8EPR2 is rated for -40 °C to +105 °C, matching the industrial temperature grade defined in its ordering code A8. This specification ensures reliable operation in demanding environments such as factory automation cabinets, outdoor energy meters, and transportation infrastructure - unlike consumer-grade variants limited to 85 °C.
How does MC34PF3000A8EPR2 support DDR3L memory power requirements?
MC34PF3000A8EPR2 supports DDR3L via two dedicated functions: SW3 provides the core VDDQ supply (0.9–1.65 V, 1.5 A), while VREFDDR delivers a precision 0.5×SW3_OUT reference (0.5–0.9 V, 10 mA). This tracking architecture ensures stable DDR3L termination voltage aligned with memory core voltage, critical for signal integrity and JEDEC compliance.
Can MC34PF3000A8EPR2 be used with input voltages above 4.5 V?
Yes - MC34PF3000A8EPR2 supports up to 5.5 V input via the VPWR pin when paired with an external P-MOSFET controlled by the LDOG pin. This front-end LDO configuration regulates VPWR down to ≤4.5 V before feeding internal regulators, enabling direct connection to common 5 V or 24 V DC systems without intermediate buck conversion.
What role does OTP memory play in MC34PF3000A8EPR2 configuration?
OTP memory in MC34PF3000A8EPR2 permanently stores startup parameters including regulator output voltages, sequencing order and timing, I²C slave address (0x08–0x0F), PWRON trigger mode (level/edge), and RESETBMCU behavior. This eliminates boot-time I²C writes and external configuration components, ensuring deterministic, repeatable power-up across all units.
Is MC34PF3000A8EPR2 pin-compatible with other PF3000 variants like MC32PF3000A8EP?
Yes - all PF3000 family members, including MC34PF3000A8EPR2 and MC32PF3000A8EP, share identical 48-pin QFN (98ASA00933D) packaging and pinout. Differences lie solely in OTP programming, temperature grading, and tape-and-reel suffix (R2); no PCB layout changes are needed when migrating between variants with matching A-code configurations.
