Product details
Overview
MC34PF3000A0EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors with LPDDR2 memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs, VREFDDR reference, and coin-cell backup support. It operates from 2.8–4.5 V input, integrates OTP-programmable startup sequencing, and powers full-system rails including processor cores, DDR memory, and peripherals in industrial embedded designs.
For engineers reviewing the MC34PF3000A0EP datasheet, MC34PF3000A0EP pinout, MC34PF3000A0EP application, or MC34PF3000A0EP equivalent, this page provides verified regulator configurations, I²C-address programmability, dynamic voltage scaling modes (PWM/PFM/APS), thermal-safe 48-QFN wettable flank package details, and validated alternatives for i.MX 6UL-based industrial control and medical monitoring systems.
Technical Context
The MC34PF3000A0EP implements a configurable multi-rail architecture: SW1A and SW1B can operate independently or combine into a single 2.75 A buck stage; SW2 supports dual output ranges (1.50–1.85 V or 2.50–3.30 V); SW3 delivers 0.90–1.65 V core supply; and SWBST provides 5.0–5.15 V at 600 mA for USB OTG. All bucks support programmable soft-start, current limiting, and DVS via I²C or OTP.
Its control logic includes OTP-configurable PWRON edge/level detection, STANDBY polarity inversion, RESETBMCU fault-mode timing (1.8 ms fault hold), and SD_VSEL-driven VCC_SD voltage selection (1.8 V or 2.85–3.3 V). The VSNVS rail supplies SNVS/SRTC at 3.0 V with coin-cell backup, while VREFDDR generates 0.5×VDDR for DDR3L/LPDDR2 compliance.

Pinout & Package
MC34PF3000A0EP uses a 48-pin QFN package (98ASA00933D), 7.0 mm × 7.0 mm with wettable flanks for automated optical inspection and robust thermal dissipation. The exposed pad (EP) must be connected to internal/external ground planes via multiple vias.

| VSNVS | Always-on RTC supply | Delivers 3.0 V @ 1.0 mA from VIN or coin cell; maintains secure real-time clock during main power loss |
| SDA / SCL | I²C interface pins | Open-drain data/clock lines; require 4.7 kΩ pull-ups to VDDIO (1.7–3.6 V) for configuration and runtime voltage adjustment |
| PWRON | Power-on control input | Configurable as level- or edge-triggered (OTP bit PWRON_CFG); supports mechanical switch debouncing up to 750 ms |
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 |
|---|---|---|---|
| MC33PF3000A7ES | Automotive-grade (−40 °C to +105 °C), same OTP option 7 (i.MX 6UL + DDR3L), but ES suffix indicates lead-free tray packaging vs. EP tape-and-reel | Qualified per AEC-Q100 Grade 2; required for automotive infotainment or ADAS companion modules | Select when automotive qualification and tray delivery are mandatory; not drop-in due to packaging and moisture sensitivity differences |
| MC34PF3000A7EP | Identical industrial-grade spec and OTP option 7, but configured for DDR3L instead of LPDDR2; shares same 48-QFN footprint and pinout | Targets i.MX 6UL systems with DDR3L memory requiring higher VDDQ (1.35 V) and different VREFDDR tracking ratio | Choose for DDR3L-based designs; requires validation of SW2 voltage range (1.5–1.85 V) and VREFDDR calibration against DDR3L JEDEC spec |
Compared with MC34PF3000A0EP, MC33PF3000A7ES adds automotive qualification at the cost of non-reel packaging, while MC34PF3000A7EP shifts memory support from LPDDR2 to DDR3L-requiring verification of VREFDDR tracking accuracy and SW2 output stability under DDR3L load transients.

FAQ
What is the input voltage range supported by the MC34PF3000A0EP?
The MC34PF3000A0EP supports an input voltage range of 2.8 V to 4.5 V when powered through the VIN pin. This range accommodates standard single-cell Li-ion batteries and regulated 3.3 V or 5 V system rails without requiring external pre-regulation. The MC34PF3000A0EP does not support the 3.7–5.5 V VPWR input path, as that configuration requires different OTP programming and external FET implementation.
Which i.MX processor variant is the MC34PF3000A0EP specifically programmed for?
The MC34PF3000A0EP is factory-programmed with OTP option 0, indicating it is configured for use with i.MX 6UL processors paired with LPDDR2 memory. Its startup sequence, voltage settings, and VREFDDR tracking behavior are optimized for this specific combination, as defined in Table 1 of the PF3000 datasheet.
Does the MC34PF3000A0EP include integrated coin-cell charging capability?
Yes, the MC34PF3000A0EP includes a dedicated LICELL pin that supports coin-cell charging and backup. When a coin cell is connected, the device maintains VSNVS at 3.0 V with 1.0 mA supply current, preserving RTC and secure non-volatile state during main power loss-critical for industrial logging and medical timestamping applications.
Can the I²C address of the MC34PF3000A0EP be changed after manufacturing?
No-the I²C address of the MC34PF3000A0EP is permanently programmed into OTP memory during manufacturing and cannot be altered in the field. It defaults to 0x08 but may be set to any value from 0x08 to 0x0F depending on the OTP configuration. Users must verify the assigned address via datasheet Table 8 or manufacturer marking before system integration.
What is the purpose of the SD_VSEL pin on the MC34PF3000A0EP?
The SD_VSEL pin on the MC34PF3000A0EP selects between two output voltage ranges for the VCC_SD LDO: logic-high sets 1.80–1.85 V for high-speed SD card interfaces, while logic-low sets 2.85–3.30 V for legacy SD/SDIO peripherals. This hardware-selectable feature eliminates the need for external voltage translators in mixed-interface designs.
