Product details
Overview
MC33PF3000A0ESR2 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 including V33 (350 mA) and VCC_SD (100 mA), RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5–0.9 V), and coin-cell charging - all in a single 48-pin QFN package for compact embedded systems.
For engineers reviewing the MC33PF3000A0ESR2 datasheet, MC33PF3000A0ESR2 pinout, MC33PF3000A0ESR2 application, or MC33PF3000A0ESR2 equivalent, this page delivers verified regulator output ranges, I²C-configurable startup sequencing, dynamic voltage scaling modes (PWM/PFM/APS), OTP-programmable power tree, and validated thermal design guidance for industrial-grade i.MX 6UL-based designs.
Technical Context
The MC33PF3000A0ESR2 implements a multi-rail architecture with configurable SW1A/SW1B pairing (independent or combined 2.75 A), programmable soft-start ramp rates (25 mV/2–4 μs), and dual-input support (VIN ≤ 4.5 V or VPWR + external PFET for 3.7–5.5 V). Its OTP memory stores startup sequence timing (0.5 ms or 2.0 ms slot increments), regulator enable order, and I²C slave address (0x08–0x0F).
Control logic integrates direct hardware interfaces - PWRON (level- or edge-triggered with 31.25–750 ms debounce), STANDBY (active-high/low configurable), RESETBMCU (fault-aware or timer-based), and SD_VSEL (dual-voltage selection for VCC_SD) - alongside I²C for runtime reconfiguration of buck output voltages, current limits, and DVS transitions.

Pinout & Package
MC33PF3000A0ESR2 uses a 48-pin QFN package (98ASA00933D, 7.0 mm × 7.0 mm, wettable flank) with exposed thermal pad (EP) tied to ground for enhanced thermal dissipation in high-power-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1AIN / SW1BIN | Buck input supply pins | Require ≥4.7 μF ceramic + 0.1 μF decoupling close to pin; VIN-referenced for ≤4.5 V operation |
| SW1ALX / SW1BLX / SW2LX / SW3LX | Switch node outputs | Connect directly to respective inductors; routing must avoid coupling with feedback traces |
| SW1AFB / SW1BFB / SW2FB / SW3FB | Voltage feedback inputs | Must be routed separately from high-current paths; terminate at output capacitor for regulation stability |
| VCC_SD / V33 / VLDO2 / VLDO4 | LDO outputs | VCC_SD supports SD card dual-voltage (1.8 V / 3.3 V) via SD_VSEL; V33 drives 3.3 V I/O rails |
| PWRON / STANDBY / RESETBMCU / INTB | Control logic I/O | PWRON configurable for mechanical switch debounce (31.25–750 ms); INTB is open-drain fault interrupt |
| SCL / SDA / VDDIO | I²C interface | VDDIO (1.7–3.6 V) powers I²C bus; SCL/SDA require 4.7 kΩ pull-ups to VDDIO |
Key Features
| Feature | Design Value |
|---|---|
| Configurable SW1A/SW1B topology | Enables either independent 1.0 A / 1.75 A operation or combined 2.75 A single-phase mode for scalable core rail delivery |
| Programmable startup sequence | 15-slot timing with 0.5 ms or 2.0 ms increments per slot; RESETBMCU deasserts 2.0 ms after final enabled regulator |
| Dual-input power architecture | Supports direct VIN connection (≤4.5 V) or VPWR + external PFET (3.7–5.5 V), enabling compatibility across battery and adapter-powered systems |
| VREFDDR generation | Derives DDR reference from SW3 output (0.5×) with <1% error; eliminates need for external precision reference IC |
| OTP-based configuration storage | Stores I²C address, PWRON mode, SD_VSEL behavior, and regulator voltages - removes boot-time I²C writes in production firmware |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3000A7ESR2 | Same architecture, −40 °C to +105 °C industrial grade, pre-programmed for i.MX 6UL + DDR3L (OTP code 7) | Targets DDR3L memory instead of LPDDR2; requires board-level validation of VREFDDR sourcing from SW3 | Select when DDR3L interface is used and extended temperature range is required without custom OTP programming |
| PF8100A0ESR2 | Higher integration: adds USB-C PD controller, 3.3 V/1 A always-on LDO, and enhanced thermal monitoring | Designed for next-gen i.MX 8M Nano; lacks LPDDR2-specific VCC_SD dual-voltage support and SW1A/B pairing flexibility | Choose for new i.MX 8M designs requiring USB-C power delivery; not drop-in compatible due to pinout and register map differences |
Compared with MC33PF3000A0ESR2, MC34PF3000A7ESR2 offers identical functionality with factory-programmed DDR3L timing but no coin-cell charging; PF8100A0ESR2 provides broader feature set for newer processors but requires PCB redesign and firmware adaptation.

FAQ
What is the input voltage range supported by the MC33PF3000A0ESR2?
The MC33PF3000A0ESR2 supports two input configurations: 2.8 V to 4.5 V when powered through the VIN pin, or 3.7 V to 5.5 V when using the VPWR pin with an external PFET. This dual-input architecture allows seamless integration into both battery-powered and adapter-fed systems without redesigning the power stage.
How does the MC33PF3000A0ESR2 handle DDR memory reference voltage generation?
The MC33PF3000A0ESR2 generates VREFDDR as 0.5 × SW3 output voltage, with tight regulation (±1% typical) and 10 mA drive capability. This eliminates the need for an external reference IC and ensures compliance with JEDEC LPDDR2 specifications when SW3 is configured to 1.35 V for 0.675 V VREFDDR.
Can the MC33PF3000A0ESR2 be used with i.MX 7 processors?
No - the MC33PF3000A0ESR2 is factory-programmed with OTP code 0 (unprogrammed) and intended for i.MX 6UL with LPDDR2. While the underlying PF3000 silicon supports i.MX 7, this specific variant lacks the pre-configured startup sequence and regulator settings required for i.MX 7 DDR3L or LPDDR3 interfaces.
What is the role of the SD_VSEL pin on the MC33PF3000A0ESR2?
The SD_VSEL pin on the MC33PF3000A0ESR2 selects between two output voltage ranges for the VCC_SD LDO: logic high configures 1.80–1.85 V for high-speed SD card operation, while logic low sets 2.85–3.30 V for legacy SD mode. The input buffer is powered by VDDIO, defaulting to high if VDDIO is absent.
Does the MC33PF3000A0ESR2 include integrated coin-cell charging capability?
Yes - the MC33PF3000A0ESR2 integrates a dedicated coin-cell charger circuit connected to the LICELL pin, enabling automatic backup power for the VSNVS rail (3.0 V, 1.0 mA). This ensures reliable real-time clock and secure non-volatile storage operation during main power loss.
