Product details
Overview
MC34PF1510A3EP from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 6UL processors with DDR3L memory, delivering 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 supports low-power IoT wearables and industrial embedded systems requiring stable multi-rail sequencing.
For engineers reviewing the MC34PF1510A3EP datasheet, MC34PF1510A3EP pinout, MC34PF1510A3EP application, or MC34PF1510A3EP equivalent, key selection criteria include its OTP-configured startup sequence for i.MX 6UL+DDR3L, −40 °C to 105 °C industrial temperature rating, 40-pin QFN package with exposed pad, and integrated coin-cell charger for RTC backup.
Technical Context
The MC34PF1510A3EP implements a dedicated front-end LDO (1500 mA input limit, up to 6.5 V operation, 22 V transient withstand) feeding VSYS, which powers all internal regulators. Its three synchronous buck converters operate at 2 MHz with programmable DVS on SW1/SW2 and fixed 1.8–3.3 V output on SW3, while LDO1/LDO3 support load-switch mode and LDO2 delivers 400 mA at 1.8–3.3 V.
OTP memory stores device-specific configuration including regulator voltages, startup/shutdown timing, soft-start profiles, and power-mode behavior (Standby/Sleep/Off). The I²C interface enables runtime control of voltage levels, current limits, and mode transitions, with interrupt (INTB) and watchdog (WDI) signals supporting system-level power management coordination.

FAQ
What is the primary processor compatibility of the MC34PF1510A3EP?
The MC34PF1510A3EP is preprogrammed in OTP memory for use with NXP i.MX 6UL processors paired with DDR3L memory. Its startup sequence, voltage setpoints, and timing parameters are specifically configured for this combination, ensuring reliable power-up without external configuration. The MC34PF1510A3EP does not support i.MX 7ULP or i.MX 6ULL out of the box.
Does the MC34PF1510A3EP support dynamic voltage scaling (DVS)?
Yes, the MC34PF1510A3EP supports DVS on its SW1 and SW2 buck converters, enabling real-time adjustment of output voltage in 12.5 mV steps. This feature is used during i.MX 6UL processor frequency scaling to optimize power consumption. DVS is disabled on SW3, which provides fixed 1.8–3.3 V outputs for DDR3L and I/O rails.
What is the function of the VSNVS pin on the MC34PF1510A3EP?
The VSNVS pin on the MC34PF1510A3EP delivers a regulated 3.0 V output at up to 2.0 mA for the Secure Non-Volatile Storage (SNVS) domain, including the real-time clock (RTC). It integrates a coin-cell charger that maintains RTC operation during main power loss. A 0.47 µF capacitor must be placed directly between VSNVS and ground for stability.
Can the MC34PF1510A3EP operate from a 5 V USB source?
Yes, the MC34PF1510A3EP accepts 5 V USB input via the VIN pin (Pin 37), which feeds the front-end LDO. This LDO regulates down to VSYS (typically ~3.7 V), powering all internal regulators. The device tolerates input transients up to +22 V and operates across 4.1–6.0 V, making it robust for unregulated USB adapter inputs.
What package type and thermal characteristics apply to the MC34PF1510A3EP?
The MC34PF1510A3EP uses a 40-pin QFN package (5.0 mm × 5.0 mm) with exposed thermal pad (EPAD, Pin 41). Its junction-to-ambient thermal resistance (RΘJA) is 17.8 °C/W on an eight-layer PCB, supporting continuous operation at full load within its −40 °C to 105 °C ambient range without forced airflow.
