Product details
Overview
MC33PF3001A7ES from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) engineered for i.MX 6UL processors with DDR3L memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A) and seven LDOs-including V33 (3.3 V, 350 mA), VLDO4 (3.3 V, 350 mA), and VSNVS (3.0 V, 1.0 mA)-in a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package rated for −40 °C to +105 °C automotive operation.
For engineers reviewing the MC33PF3001A7ES datasheet, MC33PF3001A7ES pinout, MC33PF3001A7ES application, or MC33PF3001A7ES equivalent, this page provides verified regulator output voltages, OTP-configured startup sequencing (SW1=1.4 V, SW2=3.3 V, SW3=1.35 V), I²C programmability, dynamic voltage scaling support, and confirmed thermal design guidance for industrial and automotive embedded systems.
Technical Context
The MC33PF3001A7ES implements fixed OTP-based power sequencing optimized for i.MX 6UL with DDR3L, featuring three independent synchronous buck regulators with PWM/APS/PFM mode control and integrated current limiting, plus seven LDOs with programmable output voltages and dedicated input rails (VLDO2IN, VLDO34IN, VIN2).
It integrates a coin-cell–backed RTC supply (VSNVS), SD-card dual-voltage support via SD_VSEL-controlled VCC_SD (1.80–1.85 V or 2.85–3.30 V), and optional front-end VPWR LDO using external P-MOSFET for input voltages up to 5.5 V-while maintaining internal 16 MHz trimmed oscillator-derived switching frequencies and 32 kHz startup timing reference.

Pinout & Package
MC33PF3001A7ES uses a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package (98ASA00933D) with exposed thermal pad (EP). Pin functions are validated per NXP PF3001 Rev. 5.1 datasheet Section 7.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1LX (pins 8,9) | Buck switch node | Connects directly to SW1 inductor; requires low-inductance layout to minimize EMI and switching losses |
| SW1FB (pin 6) | Voltage feedback input | Monitors SW1 output at capacitor or load; routed separately from high-current paths for regulation stability |
| VCC_SD (pin 33) | SD card I/O regulator | Output voltage set by SD_VSEL pin; supports 1.80–1.85 V or 2.85–3.30 V for high-speed SD interface compliance |
| INTB (pin 1) | Open-drain fault interrupt | Asserted low on unmasked faults (e.g., overvoltage, thermal shutdown); requires external pull-up to VDDIO |
| RESETBMCU (pin 3) | Processor reset signal | Deasserted 2.0 ms after final regulator enable; used to release i.MX 6UL from POR after full power rail stabilization |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configured startup sequence | Fixed timing and ordering (SW1→SW2→SW3→V33→VCC_SD) eliminates firmware dependency for reliable boot |
| Dynamic voltage scaling (DVS) | Programmable ramp rate (6.25 mV/μs) on SW1/SW2/SW3 enables adaptive core voltage control during CPU frequency transitions |
| Dual-voltage SD card support | VCC_SD output toggles between 1.8 V and 3.3 V ranges based on SD_VSEL logic level-enabling UHS-I and legacy SD modes |
| Always-on RTC supply with coin-cell charging | VSNVS delivers regulated 3.0 V at 1.0 mA and manages Li-ion/Li-MnO₂ coin cell charging without external circuitry |
| Front-end VPWR LDO option | External P-MOSFET (e.g., FDMA908PZ) controlled via LDOG pin allows safe operation with 4.5–5.5 V inputs while protecting internal regulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3001A7ES | Same OTP configuration and pinout; rated for −40 °C to +105 °C industrial grade (not automotive-qualified) | Suitable for non-automotive industrial systems requiring identical power tree but without AEC-Q100 compliance needs | Select MC34PF3001A7ES only if AEC-Q100 qualification is not required and cost optimization is prioritized |
| PF8100A7ES | Higher integration: includes USB Type-C PD controller, 4 buck + 10 LDOs, 16-bit ADC; different pinout and I²C address (0x09) | Targets next-gen i.MX 8M designs needing USB-C power delivery and enhanced monitoring-not drop-in compatible with i.MX 6UL | Choose PF8100A7ES only when upgrading to i.MX 8M and requiring USB-C PD, not for i.MX 6UL replacement |
Compared with MC33PF3001A7ES, MC34PF3001A7ES offers identical functionality without automotive qualification, while PF8100A7ES delivers expanded features for newer platforms but requires PCB redesign and firmware adaptation-neither serves as a pin-compatible drop-in replacement.

FAQ
What is the operating temperature range for MC33PF3001A7ES?
MC33PF3001A7ES is qualified for −40 °C to +105 °C ambient operation, meeting automotive-grade thermal requirements. This rating is explicitly defined in Table 1 of the PF3001 datasheet Rev. 5.1 for part number MC33PF3001A7ES, distinguishing it from consumer-grade MC32 variants (−40 °C to +85 °C) and industrial MC34 variants (−40 °C to +105 °C without AEC-Q100).
Does MC33PF3001A7ES support dynamic voltage scaling (DVS)?
Yes, MC33PF3001A7ES supports DVS on all three buck regulators (SW1, SW2, SW3) with programmable ramp rates-6.25 mV/μs for SW1 and SW2 per Table 4. This enables precise core voltage adjustment during i.MX 6UL frequency scaling, reducing dynamic power consumption while maintaining timing margins.
How does the SD_VSEL pin affect MC33PF3001A7ES operation?
The SD_VSEL pin on MC33PF3001A7ES selects VCC_SD output voltage: logic high yields 1.80–1.85 V for UHS-I SD cards; logic low yields 2.85–3.30 V for legacy SD. Its buffer is powered by VDDIO, and defaults to high if VDDIO is absent-ensuring safe fallback behavior during power sequencing.
Can MC33PF3001A7ES operate with a 5.0 V input supply?
Yes, MC33PF3001A7ES supports 5.0 V input via the VPWR pin using an external P-MOSFET (e.g., FDMA908PZ) controlled by the LDOG pin. When VPWR > 4.5 V, the internal front-end LDO regulates VIN to ≤4.5 V; for ≤4.5 V inputs, VIN is used directly-no external FET needed.
What is the default I²C address for MC33PF3001A7ES?
The default I²C address for MC33PF3001A7ES is 0x08, consistent across all PF3001 variants (A1–A7) per Table 4 of the datasheet. This 7-bit address is hard-coded in OTP and cannot be altered; multiple devices require address differentiation via hardware strapping or bus isolation.
