Product details
Overview
MC34PF1510A5EPR2 from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 6UL processors with DDR3 memory, featuring three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), VSNVS RTC supply (3.0 V/2.0 mA), DDR reference (VREFDDR, 0.5–0.9 V/10 mA), and I²C programmability. It delivers full-system power in low-power IoT and wearable devices.
For engineers reviewing the MC34PF1510A5EPR2 datasheet, MC34PF1510A5EPR2 pinout, MC34PF1510A5EPR2 application, or MC34PF1510A5EPR2 equivalent, key selection considerations include its industrial temperature range (−40 °C to 105 °C), OTP-configurable startup sequence, dynamic voltage scaling on SW1/SW2, and QFN40 5.0 mm × 5.0 mm package with exposed thermal pad.
Technical Context
The MC34PF1510A5EPR2 integrates a front-end LDO (1500 mA, 4.1–6.0 V input, 22 V surge tolerant), three synchronous buck regulators with internal MOSFETs and digital soft-start, and three programmable LDOs-including LDO2P7 (2.7 V/5.0 mA always-on) and USBPHY (3.3 V or 4.9 V/60 mA). Its OTP memory stores device-specific configuration including regulator voltages, timing, and power-up/down sequences.
It supports multiple operating modes-Standby, Sleep/Low-power (quiescent current ≤1.0 µA per buck), and Off (REGS_DISABLE)-with I²C interface (1.7–3.6 V VDDIO), watchdog timer (80 s period), and robust protection features including overvoltage lockout (6.5 V threshold), current limiting, and thermal shutdown.

FAQ
What is the OTP programming configuration of MC34PF1510A5EPR2?
The MC34PF1510A5EPR2 is factory-programmed with configuration code "5", which targets i.MX 6UL processors with DDR3 memory. This includes preset output voltages for SW1 (1.1 V core), SW2 (3.3 V I/O), SW3 (1.5 V DDR3), and corresponding startup timing and sequencing parameters stored in one-time-programmable memory.
Does MC34PF1510A5EPR2 support dynamic voltage scaling (DVS)?
Yes, MC34PF1510A5EPR2 supports DVS on SW1 and SW2 buck converters via I²C commands, allowing real-time adjustment of output voltage in 12.5 mV steps within the 0.6 V to 1.3875 V range. This enables precise matching to i.MX 6UL CPU core voltage requirements during frequency scaling.
What is the maximum input voltage tolerance for MC34PF1510A5EPR2?
MC34PF1510A5EPR2 VIN pin withstands DC and transient inputs up to +22 V, with overvoltage lockout triggering at 6.5 V (typical). This protects downstream circuitry during 24 VDC field bus coupling or hot-swap events in industrial environments.
How is thermal management implemented in MC34PF1510A5EPR2?
MC34PF1510A5EPR2 uses an exposed thermal pad (EPAD, Pin 41) that must be soldered to the PCB ground plane via multiple vias. Its junction-to-board thermal resistance is 8.8 °C/W, enabling reliable operation at 105 °C ambient on 8-layer boards with RΘJA = 17.8 °C/W.
Can MC34PF1510A5EPR2 power DDR3 memory directly?
Yes, MC34PF1510A5EPR2 provides dedicated DDR3 support via VREFDDR (0.5–0.9 V, 10 mA) and SW3 (programmable 1.5 V output for DDR3 termination), both electrically isolated and optimized for low-noise, high-current delivery required by i.MX 6UL DDR3 interfaces.
