Product details
Overview
MC34PF3000A1EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 7 processors with DDR3L 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, 0.5–0.9 V), and coin-cell charging. It delivers full-system power for application processors, memory, and peripherals in industrial embedded designs.
For engineers reviewing the MC34PF3000A1EP datasheet, MC34PF3000A1EP pinout, MC34PF3000A1EP application, or MC34PF3000A1EP equivalent, key selection criteria include OTP-programmable startup sequence, dynamic voltage scaling support for core rails, I²C-configurable regulator outputs, and compatibility with i.MX 7 DDR3L power tree requirements.
Technical Context
The MC34PF3000A1EP implements a SMARTMOS-based multi-rail architecture with configurable buck topology: SW1A (1.0 A) and SW1B (1.75 A) can operate independently or combine into a single 2.75 A channel. It supports three operating modes-PWM, PFM, and APS-for efficiency optimization across load ranges.
Startup sequencing is fully defined in OTP memory, enabling deterministic power-up of VCORE (0.7–1.425 V), SW2 (1.5–3.3 V), SW3 (0.9–1.65 V), V33 (2.85–3.3 V), and VCC_SD (1.8/2.85–3.3 V) without external timing components. The I²C interface (address 0x08–0x0F) allows runtime reconfiguration of output voltages, soft-start timing, and fault response.
Key Specifications

Pinout & Package
MC34PF3000A1EP uses a 48-pin QFN package (98ASA00933D), 7.0 mm × 7.0 mm, wettable flank, rated for –40 °C to +105 °C industrial operation. Exposed thermal pad (EP) must be connected to ground plane for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Signals regulator faults (OCP, UVLO, thermal) to host processor; requires external pull-up |
| SW1ALX / SW1BLX | Switch node terminals | Connect to respective inductors; shared when SW1A/B configured as single 2.75 A buck |
| SW1AFB / SW1BFB | Voltage feedback inputs | High-impedance analog inputs for closed-loop regulation; require Kelvin routing near output caps |
| VCC_SD / SD_VSEL | Dual-voltage SDIO regulator + control | VCC_SD outputs 1.8 V or 2.85–3.3 V based on logic level at SD_VSEL pin |
| VREFDDR / VINREFDDR / VHALF | DDR reference generation network | VREFDDR = 0.5 × SW3_OUT; VHALF provides half-supply bias; VINREFDDR supplies internal reference |
| PWRON / STANDBY | Power-state control inputs | PWRON initiates startup (level- or edge-triggered per OTP); STANDBY enters low-power standby mode |
| SCL / SDA / VDDIO | I²C interface | Standard open-drain bus; VDDIO (1.7–3.6 V) powers I/O buffers and sets logic thresholds |
| LICELL | Coin-cell interface | Bidirectional terminal for battery backup charging and VSNVS sourcing; bypassed with 0.1 μF |
Key Features
| Feature | Design Value |
|---|---|
| Configurable SW1A/SW1B topology | Enables either dual-rail flexibility (1.0 A + 1.75 A) or high-current single-rail (2.75 A) for i.MX 7 core domains |

| Dynamic voltage scaling (DVS) | Allows real-time adjustment of SW1A/SW1B output during operation to match CPU performance states |
| VREFDDR tracking architecture | Ensures DDR3L reference remains at exactly half of SW3 output, critical for signal integrity in high-speed memory interfaces |

FAQ
What is the operating temperature range for MC34PF3000A1EP?
MC34PF3000A1EP is rated for –40 °C to +105 °C ambient operation, qualifying it for industrial applications including fanless control panels and medical devices. This rating is confirmed in Table 1 of the PF3000 datasheet under the "MC34PF3000A*EP" part variants and applies to the full functional specification, including all buck regulators, LDOs, and RTC supply.
Does MC34PF3000A1EP support DDR3L memory voltage referencing?
Yes, MC34PF3000A1EP includes a dedicated VREFDDR regulator that outputs 0.5 × SW3_OUT (0.5–0.9 V) at 10 mA, meeting JEDEC DDR3L specifications. This tracking architecture ensures precise reference alignment with the DDR I/O supply, and is explicitly enabled in the OTP configuration for MC34PF3000A1EP's i.MX 7 with DDR3L use case.
How is the startup sequence configured on MC34PF3000A1EP?
The startup sequence of MC34PF3000A1EP is stored in one-time programmable (OTP) memory and cannot be altered post-manufacture. It defines the enable order and inter-delay (0.5 ms or 2.0 ms) for all regulators-including SW1A, SW2, SW3, V33, and VCC_SD-and is pre-programmed for i.MX 7 with DDR3L, as indicated by the "A1" suffix in the part number.
Can MC34PF3000A1EP be used with i.MX 6UL processors?
MC34PF3000A1EP is optimized for i.MX 7 with DDR3L and is not recommended for i.MX 6UL. For i.MX 6UL, NXP specifies MC34PF3000A6EP (LPDDR2) or MC34PF3000A7EP (DDR3L); using MC34PF3000A1EP would require full validation of voltage levels, sequencing, and DVS timing against i.MX 6UL datasheet requirements.
What is the purpose of the LICELL pin on MC34PF3000A1EP?
The LICELL pin on MC34PF3000A1EP serves as a bidirectional interface for coin-cell batteries: it charges a backup cell (via internal linear charger) and sources VSNVS (3.0 V, 1.0 mA) when main power is absent. This ensures continuous RTC operation and secure non-volatile state retention, as documented in Section 7.2 and Figure 4 of the PF3000 datasheet.
