Product details
Overview
MC34PF3000A5EP from NXP Semiconductors is a power management IC (PMIC) engineered for the i.MX 6SL application processor with LPDDR2 memory interface. It integrates 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), V33 (350 mA), and VSNVS (1.0 mA always-on RTC supply), plus a 5.0–5.15 V/600 mA boost regulator for USB OTG. It delivers full system power to processors, DDR memory, and peripherals in compact industrial edge devices.
For engineers reviewing the MC34PF3000A5EP datasheet, MC34PF3000A5EP pinout, MC34PF3000A5EP application, or MC34PF3000A5EP equivalent, key selection criteria include OTP-programmable startup sequence, dynamic voltage scaling for core rails, I²C-configurable regulation, and compatibility with i.MX 6SL's LPDDR2 timing and voltage requirements.
Technical Context
The MC34PF3000A5EP implements a SMARTMOS-based architecture with OTP-programmed power tree configuration, enabling deterministic startup without external sequencing components. Its SW1A/SW1B can operate independently or combine into a single 2.75 A rail, while SW2 supports dual output ranges (1.50–1.85 V or 2.50–3.30 V) for flexible SoC core and I/O domain powering.
It features integrated VREFDDR generation (0.5 × SW3_OUT, ±1% accuracy), coin-cell-backed VSNVS for secure real-time clock operation, and programmable PWRON debounce (up to 750 ms) for mechanical switch interfacing - all coordinated via a dedicated initialization state machine and I²C register map.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8–4.5 V (VIN) or 3.7–5.5 V (VPWR with external PFET); enables direct battery or adapter input without pre-regulation |
| Core Buck Regulators | SW1A: 0.7–1.425 V / 1.0 A; SW1B: 0.7–1.475 V / 1.75 A; SW2: 1.5–1.85 V or 2.5–3.3 V / 1.25 A; SW3: 0.9–1.65 V / 1.5 A - covers i.MX 6SL ARM core, SOC logic, and DDR termination |
| VCC_SD Output | 1.80–1.85 V or 2.85–3.30 V / 100 mA - dynamically selectable via SD_VSEL pin for high-speed SDIO compliance |
| VREFDDR Accuracy | 0.5 × SW3_OUT, ±1% tolerance at 10 mA - provides precise DDR2/LPDDR2 reference without external resistor divider |
| I²C Address Range | 0x08–0x0F (OTP-programmable LSBs); avoids bus conflicts in multi-PMIC or sensor-rich designs |
| Startup Sequence | 15-slot OTP-programmable timing (0.5 ms or 2.0 ms per slot); ensures safe power-up order for i.MX 6SL + LPDDR2 memory subsystem |
| Operating Temperature | −40 °C to +105 °C - qualified for industrial control and embedded gateway applications |
Pinout & Package
MC34PF3000A5EP uses a 48-pin QFN package (98ASA00933D), 7.0 mm × 7.0 mm, wettable flank, with exposed thermal pad (EP) tied to ground plane for enhanced thermal dissipation in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain fault interrupt | Asserts low on overcurrent, undervoltage, or thermal fault; requires external pull-up for host MCU notification |
| SD_VSEL | Digital input for VCC_SD range select | High = 1.80–1.85 V (SDIO mode); Low = 2.85–3.30 V (legacy SD mode); powered by VDDIO |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after final regulator enable; configurable for fault-triggered assertion (OTP_PG_EN) |
| PWRON | Power-on control input | Edge- or level-sensitive (OTP-configurable); supports debounced mechanical switch interface up to 750 ms |
| SCL/SDA | I²C interface signals | Standard open-drain bus (VDDIO-referenced); enables runtime reconfiguration of voltages, sequences, and modes |
| VIN / VPWR | Main supply inputs | VIN: primary 2.8–4.5 V input; VPWR: high-side LDO input (3.7–5.5 V) requiring external PFET for >4.5 V systems |
| SW1ALX / SW1BLX | Buck switch nodes | Independent inductor connections for SW1A/SW1B; shorted when combined into 2.75 A single-phase mode |
| VSNVS | Always-on RTC supply | 3.0 V / 1.0 mA output; powered from VIN or coin cell; maintains SNVS domain during deep sleep |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3000A6EP | OTP-programmed for i.MX 6UL with LPDDR2; identical pinout and electrical specs but different startup sequence and voltage defaults | Targeted at i.MX 6UL-based designs; not compatible with i.MX 6SL memory timing or core voltage map | Select only if migrating from i.MX 6UL to i.MX 6SL requires same PMIC footprint - requires full OTP reprogramming and validation |
| MC33PF3000A5ES | Automotive-grade (-40 °C to +105 °C), same OTP config (i.MX 6SL/LPDDR2), but uses ES package (no wettable flank) and lacks industrial qualification documentation | Approved for automotive infotainment; lacks industrial lifecycle support and AEC-Q100 stress reports required for factory equipment | Acceptable for non-safety-critical automotive prototypes; not recommended for industrial OEM production due to sourcing and traceability constraints |
Compared with MC34PF3000A5EP, MC34PF3000A6EP requires full OTP reconfiguration for i.MX 6SL use and offers no functional advantage, while MC33PF3000A5ES trades industrial BOM continuity for automotive qualification - neither serves as drop-in replacement without design review.

FAQ
What is the OTP programming configuration for MC34PF3000A5EP?
The MC34PF3000A5EP is factory-programmed for i.MX 6SL with LPDDR2 memory interface. Its OTP defines the startup sequence order, default output voltages for SW1A/B/SW2/SW3/VCC_SD/V33, I²C address (0x08), and PWRON edge-sensitivity. This configuration cannot be altered post-manufacture and is verified in Table 1 of the PF3000 datasheet Rev. 10.1.
Does MC34PF3000A5EP support both VIN and VPWR input configurations?
Yes, MC34PF3000A5EP supports dual-input operation: VIN (2.8–4.5 V) for direct battery or regulated supply, and VPWR (3.7–5.5 V) for unregulated adapters using an external PFET front-end LDO. The internal LDOG pin controls the external FET gate, and the device automatically selects the active input path based on voltage and OTP settings.
How does MC34PF3000A5EP handle DDR memory reference voltage generation?
MC34PF3000A5EP generates VREFDDR as 0.5 × SW3 output voltage with ±1% accuracy at 10 mA load. It uses internal trimming and dedicated VREFDDR regulation circuitry - no external resistors or op-amps needed. This matches LPDDR2 specification requirements and is enabled only when SW3 is active and configured within 0.9–1.65 V range.
Can MC34PF3000A5EP power both i.MX 6SL and i.MX 6UL processors interchangeably?
No, MC34PF3000A5EP is specifically OTP-configured for i.MX 6SL with LPDDR2. While electrically compatible, its startup sequence, voltage defaults, and timing parameters do not match i.MX 6UL requirements. Using it with i.MX 6UL would require disabling OTP startup and managing all rails via I²C - negating key benefits of the PMIC.
What is the role of the SD_VSEL pin on MC34PF3000A5EP?
The SD_VSEL pin on MC34PF3000A5EP selects the VCC_SD regulator output range: logic high sets 1.80–1.85 V for UHS-I SDIO mode, and logic low sets 2.85–3.30 V for legacy SD mode. It is sampled during startup and latched; changing SD_VSEL mid-operation has no effect unless the PMIC is reset or reinitialized via I²C.
