Product details
Overview
MC33PF3000A4ES from NXP Semiconductors is a pre-programmed power management IC (PMIC) optimized for i.MX 6SX application processors with DDR3 memory interface, integrating 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/1.0 mA), DDR reference (VREFDDR, 0.5×SW3_OUT), and coin-cell charger - all in a single 48-pin QFN package.
For engineers reviewing the MC33PF3000A4ES datasheet, MC33PF3000A4ES pinout, MC33PF3000A4ES application, or MC33PF3000A4ES equivalent, this PMIC delivers verified startup sequencing, I²C programmability, dynamic voltage scaling, OTP-configurable power tree, and automotive-grade thermal performance for embedded systems requiring precise rail control and low-quiescent-current operation.
Technical Context
The MC33PF3000A4ES implements a SMARTMOS-based architecture with configurable buck regulator topology: SW1A and SW1B support independent operation (1.0 A / 1.75 A) or combined 2.75 A mode, while SW2 and SW3 provide dedicated core and memory rails with programmable output voltages (SW2: 1.50–1.85 V or 2.50–3.30 V; SW3: 0.90–1.65 V). All bucks support PWM/PFM/APS modes, soft-start sequencing, and current-limit programming.
Its control logic integrates OTP-mapped startup timing (0.5 ms or 2.0 ms per slot), I²C address configuration (0x08–0x0F), PWRON edge/level sensitivity, RESETBMCU fault-mode enablement, and SD_VSEL-driven dual-voltage selection for VCC_SD (1.8 V or 2.85–3.3 V), enabling deterministic boot behavior without external configuration components.

FAQ
What is the primary application processor compatibility for MC33PF3000A4ES?
MC33PF3000A4ES is pre-programmed for use with NXP i.MX 6SX processors interfacing DDR3 memory, as indicated by its OTP code "4" in Table 1 of the PF3000 datasheet. It is not configured for i.MX 7, i.MX 6SL, or i.MX 6UL variants - those require different part numbers (e.g., MC33PF3000A1ES, A5ES, A6ES). The device's internal power tree and startup sequence are hardened for i.MX 6SX voltage domains and timing requirements.
Does MC33PF3000A4ES support DDR3L or only standard DDR3 memory?
MC33PF3000A4ES is programmed for standard DDR3 (not DDR3L), as confirmed by its ordering code "4 (i.MX 6SX with DDR3)" in Table 1. While VREFDDR derives from SW3 output and supports adjustable ranges (0.5×SW3_OUT), the OTP configuration fixes SW3 startup voltage and sequencing to match standard DDR3 VDDQ (1.5 V) and termination requirements - DDR3L compatibility would require different OTP settings found in MC33PF3000A3ES (code "3", i.MX 6SX with DDR3L).
How does the VCC_SD regulator voltage selection work on MC33PF3000A4ES?
MC33PF3000A4ES uses the SD_VSEL pin (Pin 2) to select VCC_SD output: logic LOW configures 2.85–3.30 V for standard SD cards, while logic HIGH selects 1.80–1.85 V for UHS-I SDIO operation. The SD_VSEL buffer is powered by VDDIO; if VDDIO is absent, the default logic HIGH forces 1.8 V mode. This dual-range capability is retained across all PF3000 variants, including MC33PF3000A4ES, and is implemented in hardware without OTP dependency.
Can MC33PF3000A4ES operate with a 5.0 V input supply?
Yes - MC33PF3000A4ES supports 3.7–5.5 V input via the VPWR pin (Pin 31) when used with an external P-channel MOSFET as a front-end LDO, limiting internal regulator input to ≤4.5 V. Direct 5.0 V application to VIN (Pin 42) is not permitted; doing so exceeds the 4.5 V absolute maximum rating. The VPWR path must be implemented per Figure 4 and Section 8.2 of the datasheet to safely accommodate 5.0 V system rails.
What is the function of the LICELL pin on MC33PF3000A4ES?
The LICELL pin (Pin 36) on MC33PF3000A4ES serves as bidirectional coin-cell interface: it charges a 3 V lithium cell (via internal linear charger) when main power is present and backs up the VSNVS rail (3.0 V, 1.0 mA) during main power loss. This preserves RTC time, secure non-volatile registers, and SNVS domain state - critical for automotive and medical applications requiring persistent timekeeping and cryptographic key retention across power cycles.
