NXP Semiconductors MC34PF1510A7EP

Overview

MC34PF1510A7EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors in industrial IoT and wearable devices. It integrates three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), VSNVS (3.0 V/2.0 mA), DDR reference (VREFDDR, 0.5–0.9 V), and I²C programmable OTP configuration. Its −40 °C to 105 °C operating range supports rugged embedded deployments.

For engineers reviewing the MC34PF1510A7EP datasheet, MC34PF1510A7EP pinout, MC34PF1510A7EP application, or MC34PF1510A7EP equivalent, key selection criteria include its preprogrammed i.MX 6UL + LPDDR2 configuration, 40-pin QFN package with exposed thermal pad, dynamic voltage scaling on SW1/SW2, ULP-mode quiescent current of 1.0 µA per buck, and industrial-grade temperature rating.

Technical Context

The MC34PF1510A7EP implements a front-end LDO (1500 mA, up to 6.5 V input) feeding VSYS, which powers three synchronous buck regulators with internal MOSFETs and digital soft-start. SW1 and SW2 support dynamic voltage scaling across 12.5 mV steps (0.6–1.3875 V) or variable steps (1.1–3.3 V); SW3 delivers fixed 1.8–3.3 V outputs without DVS.

Its digital core includes OTP memory for user-defined startup/power-down sequences, I²C interface (1.7–3.6 V VDDIO), and dedicated control signals (PWRON, STANDBY, ONKEY, WDI) enabling full system-level power state management - including Standby, Sleep/Low-power, and Off (REGS_DISABLE) modes - with watchdog timer (80 s period) and interrupt-driven status reporting via INTB.

FAQ

What is the operating temperature range of the MC34PF1510A7EP?

The MC34PF1510A7EP is rated for an industrial ambient operating temperature range of −40 °C to 105 °C, as confirmed in Table 3 of the official NXP datasheet. This rating applies specifically to the MC34PF1510A7EP variant and enables deployment in harsh environments such as factory automation equipment and outdoor gateways without thermal derating.

Which i.MX processor does the MC34PF1510A7EP support out of the box?

The MC34PF1510A7EP is preprogrammed with OTP Code 7 for i.MX 6UL with LPDDR2 memory, as explicitly stated in Table 1 of the NXP PF1510 datasheet. This configuration defines the startup sequence, voltage levels, and timing parameters required for seamless integration with i.MX 6UL SoCs using LPDDR2 DRAM.

Does the MC34PF1510A7EP include a real-time clock (RTC) power supply?

Yes, the MC34PF1510A7EP provides a dedicated VSNVS output (Pin 30) delivering 3.0 V at 2.0 mA for RTC backup, with integrated coin-cell charging capability via the LICELL pin (Pin 31). This ensures continuous timekeeping and register retention during main power loss, as detailed in Section 1.1 and Figure 2 of the datasheet.

Can the MC34PF1510A7EP be used with i.MX 7ULP processors?

No - the MC34PF1510A7EP is configured exclusively for i.MX 6UL with LPDDR2 (Code 7). For i.MX 7ULP support, NXP specifies MC32PF1510A2EP or MC34PF1510A2EP (Code 2 or 4), which implement different OTP sequences and voltage profiles optimized for LPDDR3 memory and 7ULP's power domains.

What package type and pin count does the MC34PF1510A7EP use?

The MC34PF1510A7EP uses a 40-pin QFN package measuring 5.0 mm × 5.0 mm with an exposed thermal pad (EPAD), as documented in Table 1 and Figure 4 of the NXP datasheet. This package is mechanically and thermally identical across all PF1510 variants, enabling layout reuse between consumer and industrial versions.
