Product details
Overview
MC34PF3000A2EPR2 from NXP Semiconductors is a pre-programmed power management IC (PMIC) optimized for i.MX 7 processors with LPDDR3 memory, integrating four buck regulators (SW1A/B up to 2.75 A combined), six LDOs, RTC supply (VSNVS, 3.0 V/1.0 mA), DDR reference (VREFDDR, 0.5×VDDR, 10 mA), and coin-cell charging. It delivers full-system power for application processors, memory, and peripherals in space-constrained industrial embedded designs.
For engineers reviewing the MC34PF3000A2EPR2 datasheet, MC34PF3000A2EPR2 pinout, MC34PF3000A2EPR2 application, or MC34PF3000A2EPR2 equivalent, this page provides verified regulator configurations, I²C-address programmability, OTP-based startup sequencing, dynamic voltage scaling support, and thermal-aware 48-pin QFN wettable flank package details - all specific to the A2 programming variant for i.MX 7 + LPDDR3 systems.
Technical Context
The MC34PF3000A2EPR2 implements a multi-rail SMARTMOS PMIC architecture with configurable SW1A/SW1B operation (independent 1.0 A / 1.75 A or combined 2.75 A), programmable soft-start ramp rates (25 mV/2–4 μs), and three operating modes per buck (PWM, PFM, APS). Its OTP memory stores startup sequence timing (0.5 ms or 2.0 ms slot resolution), regulator voltages, and I²C slave address (0x08–0x0F).
Control logic includes dedicated digital interface pins: PWRON (edge- or level-sensitive with hardware debounce), STANDBY (active-high/low configurable), RESETBMCU (fault-mode or timer-based reset assertion), and SD_VSEL (dual-range VCC_SD selection). The device supports VIN input ≤4.5 V or VPWR input up to 5.5 V via external PFET front-end LDO.
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 flexible system-level power path design |
| SW1A/B Configuration | Configurable as independent 1.0 A / 1.75 A regulators or combined 2.75 A single-phase output; matches i.MX 7 core rail requirements |
| VCC_SD Output Range | 1.80–1.85 V or 2.85–3.30 V (selected by SD_VSEL); supports dual-voltage SD card interfaces |
| VREFDDR Accuracy | 0.5 × SW3 output voltage, ±1% typical; provides precise DDR3L/LPDDR3 reference without external components |
| I²C Address | Programmable from 0x08 to 0x0F via OTP; avoids bus conflicts in multi-PMIC or mixed-device systems |
| Startup Sequence | OTP-programmable per-regulator slot (1–15 positions, 0.5/2.0 ms step); ensures safe, deterministic power-up of i.MX 7 subsystems |
| Operating Temperature | −40 °C to +105 °C; qualified for industrial applications including edge gateways and HMI controllers |
Pinout & Package
MC34PF3000A2EPR2 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-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain fault interrupt output | Asserts low on overcurrent, undervoltage, or thermal fault; requires external pull-up for processor notification |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after final regulator enable (timer mode) or only if no startup faults occur (fault mode) |
| PWRON | Power-on control input | Configurable edge- or level-sensitive; supports mechanical switch debouncing (31.25–750 ms falling-edge delay) |
| SD_VSEL | Digital select for VCC_SD range | High = 1.80–1.85 V; Low = 2.85–3.30 V; defaults high if VDDIO is invalid |
| SCL/SDA | I²C interface signals | Open-drain bus lines; require 4.7 kΩ pull-ups to VDDIO (1.7–3.6 V); support OTP configuration and runtime reprogramming |
| SW1ALX/SW1BLX | Switch node outputs | Connect to respective inductors; shorted together when SW1A/B operate in combined 2.75 A mode |
| GNDREF1/GNDREF2/GNDREF | Separate analog ground references | Isolate high-current buck return paths from core and LDO reference grounds to minimize noise coupling |
| EP | Exposed thermal pad | Must be connected to internal/external ground planes via multiple vias; critical for thermal performance at full load |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configurable startup sequence | Enables deterministic, fault-tolerant power-up of i.MX 7 cores, DDR, and peripherals without external sequencers |
| SW1A/SW1B flexible topology | Reduces BOM count by supporting either dual-core rail separation or single high-current VCOREDIG supply |
| VREFDDR generation | Eliminates external resistor divider and op-amp; delivers stable 0.5×VDDR with <±1% error for LPDDR3 compliance |
| VSNVS always-on regulator/switch | Provides 3.0 V/1.0 mA to i.MX SNVS domain from VIN or coin cell; maintains RTC and secure boot state during main power loss |
| Dynamic voltage scaling (DVS) | Supports real-time core voltage adjustment via I²C; reduces active power consumption during variable workload conditions |
| VPWR front-end LDO option | Allows use with 5.5 V inputs via external P-MOSFET; keeps internal regulator inputs ≤4.5 V for reliability and efficiency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3000A1EPR2 | OTP programmed for i.MX 7 with DDR3L (not LPDDR3); VREFDDR derived from different source; identical pinout and package | Targeted at DDR3L-based i.MX 7 designs; lacks LPDDR3-specific timing and voltage calibration | Select A1EPR2 only for DDR3L memory interfaces; A2EPR2 is mandatory for LPDDR3 compliance |
| MC34PF3000A3EPR2 | OTP programmed for i.MX 6SX with DDR3L; different regulator startup sequence, SW2 voltage range (1.5–1.85 V only), and no LPDDR3 VREFDDR mapping | Designed for i.MX 6SX SoC; incompatible with i.MX 7 core voltage profiles and memory controller signaling | A3EPR2 is not functionally substitutable for i.MX 7 systems; verify SoC compatibility before substitution |
Compared with MC34PF3000A1EPR2 and MC34PF3000A3EPR2, the MC34PF3000A2EPR2 uniquely supports LPDDR3-specific VREFDDR derivation, i.MX 7 core rail voltage ranges, and OTP-locked startup timing validated for that SoC-memory combination - making it non-interchangeable without board-level validation.

FAQ
What is the OTP programming configuration of MC34PF3000A2EPR2?
The MC34PF3000A2EPR2 is factory-programmed with OTP settings optimized for i.MX 7 processors using LPDDR3 memory. This includes VREFDDR derivation from SW3, startup sequence timing aligned to i.MX 7 boot requirements, SW1A/B combined-mode default, and I²C address set to 0x08. These values are permanently stored and cannot be modified post-manufacture.
Does MC34PF3000A2EPR2 support both VIN and VPWR input configurations?
Yes, MC34PF3000A2EPR2 supports dual-input operation: VIN (2.8–4.5 V) for direct connection to batteries or regulated supplies, and VPWR (3.7–5.5 V) when used with an external P-MOSFET front-end LDO. The VPWR path routes through LDOG to control the external FET gate, enabling safe operation with higher input voltages while protecting internal regulators.
How does the SD_VSEL pin affect VCC_SD regulation in MC34PF3000A2EPR2?
In MC34PF3000A2EPR2, the SD_VSEL pin selects between two fixed VCC_SD output ranges: logic high sets 1.80–1.85 V for high-speed SD card operation, and logic low sets 2.85–3.30 V for legacy SD or eMMC interfaces. The input buffer is powered by VDDIO; if VDDIO is absent, SD_VSEL defaults high, ensuring safe low-voltage operation during initialization.
Can MC34PF3000A2EPR2 be used with i.MX 6UL processors?
No - MC34PF3000A2EPR2 is specifically configured for i.MX 7 with LPDDR3 and is not compatible with i.MX 6UL. For i.MX 6UL designs, NXP specifies MC34PF3000A6EPR2 (LPDDR2) or MC34PF3000A7EPR2 (DDR3L). Using MC34PF3000A2EPR2 with i.MX 6UL may result in incorrect VREFDDR derivation, improper core voltage sequencing, and boot failure.
What thermal management provisions does MC34PF3000A2EPR2 require on PCB?
MC34PF3000A2EPR2 requires robust thermal design: the exposed pad (EP) must be connected to inner and outer ground planes using ≥6 thermal vias (0.3 mm diameter), and copper pour around GNDREF1/GNDREF2/GNDREF pins must be isolated from high-current return paths. Ambient temperature must remain ≤+105 °C, and junction temperature must stay below 125 °C under full load per JEDEC JESD51-2.
