Product details
Overview
MC34PF3000A3EPR2 from NXP Semiconductors is a pre-programmed power management IC (PMIC) optimized for i.MX 6SX application processors with DDR3L memory, integrating four buck regulators (SW1A/B up to 2.75 A combined), six LDOs, RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5×VDDR), and coin-cell charging. It delivers full-system power for ARM-based industrial embedded designs requiring tight sequencing and dynamic voltage scaling.
For engineers reviewing the MC34PF3000A3EPR2 datasheet, MC34PF3000A3EPR2 pinout, MC34PF3000A3EPR2 application, or MC34PF3000A3EPR2 equivalent, key selection criteria include its OTP-configured startup sequence for i.MX 6SX, VIN/VPWR dual-input support (2.8–4.5 V or 3.7–5.5 V), I²C programmability, and wettable-flank 48-QFN package for automated optical inspection.
Technical Context
The MC34PF3000A3EPR2 implements a multi-rail architecture with configurable SW1A/SW1B operation-either as independent 1.0 A / 1.75 A buck regulators or combined into a single 2.75 A channel-with programmable soft-start ramp (25 mV/2 µs or 4 µs), PWM/PEM/APS modes, and dynamic voltage scaling for core rails. Its OTP memory stores startup timing, voltage setpoints, and I²C address (0x08–0x0F), eliminating external configuration components.
Control logic includes dedicated digital interface pins: PWRON (edge- or level-sensitive with hardware debounce), STANDBY (active-high/low configurable), RESETBMCU (fault-aware or timer-based reset assertion), and SD_VSEL (dual-range VCC_SD selection). The device supports user-defined Standby, Sleep/LPSR, and Off states, with INTB providing open-drain fault signaling across all regulated outputs.

FAQ
What is the OTP configuration of MC34PF3000A3EPR2?
MC34PF3000A3EPR2 is factory-programmed with OTP settings for i.MX 6SX processors using DDR3L memory, including startup sequence order, SW2 output range (1.50–1.85 V), VCC_SD voltage selection logic, and I²C address 0x08. These parameters are fixed and cannot be modified post-shipment.
Does MC34PF3000A3EPR2 support both VIN and VPWR input paths?
Yes, MC34PF3000A3EPR2 supports dual-input architecture: VIN accepts 2.8–4.5 V for direct battery or low-voltage DC-DC input, while VPWR (with external PFET) enables 3.7–5.5 V operation-protecting internal regulators from overvoltage in higher-input industrial systems.
How does the VREFDDR output relate to SW3 on MC34PF3000A3EPR2?
On MC34PF3000A3EPR2, VREFDDR is internally generated as 0.5 × the SW3 output voltage, with ±1% accuracy. This eliminates external resistor dividers and ensures precise DDR3L reference tracking as SW3 dynamically scales for memory VDDQ requirements.
Can MC34PF3000A3EPR2 be used with i.MX 7 processors?
No-MC34PF3000A3EPR2 is specifically OTP-programmed for i.MX 6SX with DDR3L. For i.MX 7, NXP specifies MC32PF3000A1ES (DDR3L) or MC32PF3000A2ES (LPDDR3); using MC34PF3000A3EPR2 with i.MX 7 may result in incorrect voltage sequencing or unsupported rail configurations.
What is the purpose of the wettable flank package on MC34PF3000A3EPR2?
The wettable flank QFN package (98ASA00933D) on MC34PF3000A3EPR2 enables automated optical inspection (AOI) of solder joints during SMT assembly-critical for industrial and medical manufacturing where zero-defect soldering is mandated and rework is costly or prohibited.
