Product details
Overview
MC34PF3000A6EP from NXP Semiconductors is a power management IC (PMIC) engineered for the i.MX 6UL application processor 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 charging - all in a single 48-pin QFN package. It powers full-system rails including CPU cores, DDR I/O, SD card interface, and peripherals in compact embedded designs.
For engineers reviewing the MC34PF3000A6EP datasheet, MC34PF3000A6EP pinout, MC34PF3000A6EP application, or MC34PF3000A6EP equivalent, this page delivers verified regulator configurations, OTP-programmable startup sequencing, I²C address flexibility (0x08–0x0F), dynamic voltage scaling support, and industrial-grade thermal performance for i.MX 6UL-based platforms.
Technical Context
The MC34PF3000A6EP implements a configurable multi-rail architecture with SW1A/SW1B capable of independent operation or combined 2.75 A output, SW2 supporting dual-voltage ranges (1.50–1.85 V or 2.50–3.30 V), and SW3 optimized for core logic (0.90–1.65 V). Its OTP memory stores startup sequence timing, regulator voltages, PWRON edge/level configuration, and I²C slave address - eliminating external configuration components.
Control logic integrates direct hardware interfaces (PWRON, STANDBY, RESETBMCU, INTB, SD_VSEL) alongside I²C for runtime reconfiguration. The VSNVS rail provides always-on 3.0 V at 1.0 mA for secure real-time clock backup, while VREFDDR delivers programmable 0.5×SW3_OUT (5–900 mV) for DDR memory reference compliance.

FAQ
What is the primary target processor for MC34PF3000A6EP?
The MC34PF3000A6EP is specifically configured for the NXP i.MX 6UL application processor with LPDDR2 memory, as indicated by its OTP programming option '6' in Table 1. It delivers optimized voltage rails - including SW3 for core logic, VREFDDR for DDR I/O, and VCC_SD for SD card interface - matching the i.MX 6UL power tree requirements without external configuration.
Does MC34PF3000A6EP support dynamic voltage scaling (DVS)?
Yes, MC34PF3000A6EP supports DVS on SW1A, SW1B, SW2, and SW3 buck regulators. Each regulator's output voltage can be adjusted in real time via I²C writes to functional registers (e.g., SW1AVOLT), enabling adaptive power management during CPU frequency scaling or peripheral state changes in i.MX 6UL-based systems.
How is the VCC_SD regulator voltage selected on MC34PF3000A6EP?
The VCC_SD regulator voltage on MC34PF3000A6EP is selected dynamically using the SD_VSEL pin: logic HIGH sets output to 1.80–1.85 V (for high-speed SD card operation), while logic LOW selects 2.85–3.30 V (for general-purpose I/O). The SD_VSEL buffer is powered by VDDIO, defaulting to HIGH if VDDIO is absent - ensuring safe boot behavior.
Can MC34PF3000A6EP operate with input voltages above 4.5 V?
Yes, MC34PF3000A6EP supports up to 5.5 V input when using the VPWR pin with an external P-channel MOSFET as a front-end LDO. This configuration limits internal regulator input to ≤4.5 V while maintaining compatibility with higher-voltage battery or adapter sources - a capability confirmed in Section 8.2 and Table 3 of the datasheet.
What is the function of the VSNVS rail on MC34PF3000A6EP?
The VSNVS rail on MC34PF3000A6EP provides a dedicated 3.0 V, 1.0 mA always-on supply for the i.MX 6UL's Secure Non-Volatile Storage (SNVS) domain and real-time clock. It can be powered from VIN or a backup coin cell (via LICELL pin), ensuring continuous timekeeping and cryptographic key retention during main power loss - critical for industrial logging and security applications.
