Product details
Overview
MC34PF3000A8EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors with DDR3 memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs including V33 (350 mA) and VCC_SD (100 mA), and integrated coin-cell charging - enabling full-system power for industrial embedded designs.
For engineers reviewing the MC34PF3000A8EP datasheet, MC34PF3000A8EP pinout, MC34PF3000A8EP application, or MC34PF3000A8EP equivalent, this page provides verified regulator configurations, OTP-programmable startup sequencing, I²C address flexibility (0x08–0x0F), dynamic voltage scaling support, and industrial-grade thermal operation (−40 °C to +105 °C).
Technical Context
The MC34PF3000A8EP implements a multi-rail architecture with configurable SW1A/SW1B pairing (independent or combined 2.75 A), programmable soft-start ramp rates (25 mV/2 µs or 4 µs), and dual-mode PWRON control (level- or edge-sensitive). Its OTP memory stores startup sequence timing (0.5 ms or 2.0 ms slots), regulator voltages, and I²C slave address (0x08–0x0F).
It supports DDR3-compatible VREFDDR generation (0.5 × SW3 output, 10 mA), VSNVS always-on supply (3.0 V, 1.0 mA), and VPWR front-end LDO interface for >4.5 V input systems. All seven LDOs - VLDO1 (100 mA), VLDO2 (250 mA), VLDO3 (100 mA), VLDO4 (350 mA), VCC_SD (100 mA), V33 (350 mA), and VSNVS - are individually enabled and sequenced via OTP or real-time I²C writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 4.5 V (VIN) or 3.7 V to 5.5 V (VPWR); enables direct battery or adapter input without external pre-regulation |
| SW1A Output | 0.70–1.425 V or 1.8/3.3 V, 1.0 A; powers i.MX 6UL ARM core with DVS support |
| SW1B Output | 0.70–1.475 V, 1.75 A; configurable as independent rail or paired with SW1A for 2.75 A total |
| V33 Output | 2.85–3.30 V, 350 mA; supplies i.MX 6UL GPIO, USB PHY, and peripheral I/O domains |
| VREFDDR Output | 0.5 × SW3 output (0.45–0.825 V), 10 mA; precision reference for DDR3 termination and calibration |
| OTP Memory | One-time programmable storage for startup sequence, regulator voltages, PWRON mode, and I²C address - eliminates boot-time configuration overhead |
| Operating Temperature | −40 °C to +105 °C; qualified for industrial control, medical monitoring, and energy management applications |
Pinout & Package
MC34PF3000A8EP 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) serves as ground return for buck/boost regulators and must be connected to inner/external ground planes via multiple vias.
| 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 |
| SW1ALX / SW1BLX | Switch node outputs | Drive external inductors; SW1A/SW1B can operate independently or share one inductor in parallel mode |
| VIN / VPWR | Main power inputs | VIN accepts ≤4.5 V directly; VPWR enables external PFET-based LDO for 4.5–5.5 V systems |
| SCL / SDA | I²C interface pins | Support real-time register access and runtime reconfiguration; VDDIO-supplied (1.7–3.6 V), 4.7 kΩ pull-ups required |
| PWRON | Power-on control input | Configurable as level- or edge-triggered; includes hardware debounce (31.25–750 ms) for mechanical switch interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Four configurable buck regulators | SW1A (1.0 A) and SW1B (1.75 A) support independent operation or combined 2.75 A mode for scalable core power delivery |
| OTP-programmable startup sequence | 15-slot timing (0.5/2.0 ms per slot) with per-regulator enable order - ensures safe power-up of i.MX 6UL subsystems |
| Dual-voltage VCC_SD LDO | 1.80–1.85 V or 2.85–3.30 V output selectable via SD_VSEL pin - matches SD card interface voltage requirements |
| VREFDDR generation | Derives DDR3 reference from SW3 output (0.5× ratio) with 10 mA drive - eliminates external resistor divider and improves accuracy |
| Coin-cell backup & charging | LICELL pin supports rechargeable coin cell (e.g., CR2032) with charge control - maintains RTC and SNVS state during main power loss |

FAQ
What is the operating temperature range for MC34PF3000A8EP?
MC34PF3000A8EP is rated for −40 °C to +105 °C ambient operation, qualifying it for industrial environments such as factory automation controllers, outdoor energy gateways, and medical diagnostic equipment where extended thermal margins are required. This range is validated per JEDEC JESD22-A104 and applies to the full functional specification including all buck regulators, LDOs, and OTP programming.
How does MC34PF3000A8EP support DDR3 memory power requirements?
MC34PF3000A8EP supports DDR3 via its dedicated VREFDDR output, which generates a precise 0.5 × SW3 voltage (e.g., 0.675 V when SW3 = 1.35 V) with 10 mA drive capability. It also supplies VCORE (1.1 V), VDD_SOC (1.0 V), and V33 (3.3 V) rails required by i.MX 6UL DDR3 interfaces - all sequenced via OTP to meet JEDEC tINIT and tMRD timing.
Can MC34PF3000A8EP be used with input voltages above 4.5 V?
Yes - MC34PF3000A8EP supports up to 5.5 V input using the VPWR pin and an external P-channel MOSFET to implement a front-end LDO. When VPWR is used, VIN is disconnected from internal regulators, allowing safe operation with 5 V adapters or 2S Li-ion batteries while maintaining 4.5 V max on internal switching stages.
What is the purpose of the SD_VSEL pin on MC34PF3000A8EP?
The SD_VSEL pin on MC34PF3000A8EP selects between two output voltage ranges for the VCC_SD LDO: logic high sets 1.80–1.85 V (for UHS-I SD cards), and logic low sets 2.85–3.30 V (for legacy SD/SDIO). The pin is powered by VDDIO, and defaults to high if VDDIO is absent - ensuring safe default behavior during power-up.
Does MC34PF3000A8EP include battery backup capability?
Yes - MC34PF3000A8EP integrates a coin-cell charger circuit accessible via the LICELL pin, supporting standard CR2032 cells. It provides regulated charging current and automatic switchover to maintain VSNVS (3.0 V, 1.0 mA) during main power loss - preserving RTC, secure non-volatile storage, and tamper logs in industrial and security applications.
