Product details
Overview
MC34PF3000A4EPR2 from NXP Semiconductors is a pre-programmed power management IC (PMIC) optimized for i.MX 6SX processors with DDR3 memory, integrating four buck regulators (SW1A/B up to 2.75 A combined), six LDOs (including V33 at 350 mA and VLDO2 at 250 mA), RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5–0.9 V), and coin-cell charging. It powers full application processor systems in industrial edge devices requiring tight sequencing and dynamic voltage scaling.
For engineers reviewing the MC34PF3000A4EPR2 datasheet, MC34PF3000A4EPR2 pinout, MC34PF3000A4EPR2 application, or MC34PF3000A4EPR2 equivalent, key selection criteria include its OTP-configured startup sequence for i.MX 6SX+DDR3, 48-pin QFN wettable flank package, I²C programmability, and support for VPWR front-end LDO operation above 4.5 V input.
Technical Context
The MC34PF3000A4EPR2 implements a multi-rail architecture with configurable SW1A/SW1B buck pairing (2.75 A shared or 1.0 A + 1.75 A independent), SW2 (1.25 A, dual-range 1.5–1.85 V or 2.5–3.3 V), and SW3 (1.5 A, 0.9–1.65 V), all supporting PWM/PPM/APS modes and programmable soft-start. Its OTP memory stores regulator voltages, sequencing slots (0.5 ms or 2.0 ms step), and PWRON edge/level configuration - eliminating external configuration components.
It features dedicated analog blocks: VREFDDR (10 mA, 0.5×SW3_OUT tracking), VSNVS (3.0 V, 1.0 mA always-on switch/LDO), and integrated coin-cell charger (LICELL). Control logic includes open-drain INTB fault signaling, RESETBMCU (2.0 ms post-sequence deassertion), STANDBY mode entry, and SD_VSEL-driven VCC_SD voltage selection (1.8 V or 3.15 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A4ES | Same OTP configuration (i.MX 6SX + DDR3) but rated for −40 °C to +105 °C automotive temperature range; identical pinout and electrical specs | Targeted for automotive infotainment head units rather than industrial equipment | Select MC33PF3000A4ES only if AEC-Q100 qualification and extended temp range are required; otherwise MC34PF3000A4EPR2 is optimal for industrial use |
| MC34PF3000A3ES | OTP programmed for i.MX 6SX with DDR3L (lower voltage DDR), not DDR3; VREFDDR range and SW2 settings differ accordingly | Suitable for DDR3L-based designs where memory operates at 1.35 V instead of 1.5 V | Use MC34PF3000A3ES only when DDR3L memory is confirmed; mismatched OTP may cause incorrect VREFDDR or core rail voltages |
Compared with MC33PF3000A4ES and MC34PF3000A3ES, MC34PF3000A4EPR2 provides the exact OTP configuration, industrial temperature rating, and wettable flank QFN package needed for i.MX 6SX systems with standard DDR3 memory - avoiding firmware workarounds or hardware redesign.

FAQ
What is the OTP programming configuration of MC34PF3000A4EPR2?
The MC34PF3000A4EPR2 is factory-programmed with OTP settings optimized for the i.MX 6SX processor paired with standard DDR3 memory. This includes startup sequence timing, SW1A/B configuration as independent regulators, SW2 output set to 1.50–1.85 V range, and VREFDDR tracking enabled. The OTP cannot be rewritten after shipment.
Does MC34PF3000A4EPR2 support input voltages above 4.5 V?
Yes, MC34PF3000A4EPR2 supports 3.7–5.5 V input when using the VPWR pin with an external P-MOSFET controlled by the LDOG pin. This front-end LDO configuration limits internal regulator input to ≤4.5 V, protecting the IC while enabling compatibility with common 5 V system rails.
How does the VREFDDR output relate to other rails in MC34PF3000A4EPR2?
In MC34PF3000A4EPR2, the VREFDDR output is dynamically tracked to 0.5 × the SW3 output voltage, ranging from 0.5 V to 0.9 V. This eliminates need for external resistor dividers and ensures precise DDR3 termination voltage alignment with core memory supply, improving signal integrity and timing margin.
Can MC34PF3000A4EPR2 operate without a coin cell connected?
MC34PF3000A4EPR2 can operate without a coin cell for normal system power-up and regulation, but VSNVS functionality (always-on RTC domain) requires either VIN ≥ 2.85 V or a valid coin cell. Without either, Standby mode entry/exit becomes unreliable per datasheet Section 8.3.1.2.
What is the purpose of the SD_VSEL pin on MC34PF3000A4EPR2?
The SD_VSEL pin on MC34PF3000A4EPR2 selects between two output voltage ranges for 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 legacy SD interfaces. The pin is powered by VDDIO and defaults high if VDDIO is absent.
