NXP Semiconductors MC34PF1510A0EP

Overview

MC34PF1510A0EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL/6ULL/7ULP application processors in industrial IoT and wearable systems. 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 control - delivering full-system power for processors, memory, and peripherals within −40 °C to 105 °C ambient range.

For engineers reviewing the MC34PF1510A0EP datasheet, MC34PF1510A0EP pinout, MC34PF1510A0EP application, or MC34PF1510A0EP equivalent, this page provides verified electrical specs, thermal ratings, regulator sequencing behavior, OTP-configurable startup/power-down sequences, and industrial-grade package validation for i.MX-based embedded designs requiring robust low-power operation and DDR3L/LPDDR3 compatibility.

Technical Context

The MC34PF1510A0EP implements a front-end LDO (1500 mA, up to 6.5 V input) feeding VSYS, which powers three synchronous buck regulators with dynamic voltage scaling (SW1/SW2) and fixed-output SW3 (1.8–3.3 V). Its digital core uses OTP memory to store user-defined startup timing, soft-start profiles, and regulator enable/disable sequences - enabling deterministic power-up across i.MX variants without external firmware.

Regulator control is executed via I²C interface (1.7–3.6 V VDDIO), supporting standby/sleep/off modes with <1.5 μA quiescent current in low-power mode. The device includes dedicated USB_PHY LDO (4.9 V or 3.3 V, 60 mA), always-on LDO2P7 (2.7 V, 5.0 mA), coin-cell charger (LICELL), and RTC supply (VSNVS), all validated for industrial temperature operation (−40 °C to 105 °C).

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range of the MC34PF1510A0EP?

The MC34PF1510A0EP is rated for industrial ambient operation from −40 °C to 105 °C, validated per JEDEC JESD51 thermal testing standards. This range covers demanding environments such as factory floor gateways, outdoor sensor nodes, and vehicle-mounted edge devices where thermal cycling and sustained high-temperature operation are expected. The device's R_ΘJB = 8.8 °C/W and junction-to-case bottom thermal resistance of 1.4 °C/W ensure reliable performance under continuous load at maximum ambient.

Does the MC34PF1510A0EP support dynamic voltage scaling (DVS)?

Yes, the MC34PF1510A0EP supports DVS on SW1 and SW2 buck converters, allowing real-time adjustment of output voltage in 12.5 mV steps between 0.6 V and 1.3875 V. This feature enables synchronization with i.MX processor DVFS states to minimize active power consumption. DVS is controlled via I²C register writes and requires OTP configuration to enable the DVS mode - confirmed in the PF1510 datasheet Section 5.3.2.

What is the purpose of the LICELL pin on the MC34PF1510A0EP?

The LICELL pin on the MC34PF1510A0EP serves as both input and output for a coin-cell battery, enabling charging from the VSYS rail and providing backup power to the VSNVS (3.0 V) RTC supply during main power loss. It includes integrated charge control circuitry and requires only a 0.1 µF bypass capacitor. This eliminates external charging ICs and ensures uninterrupted real-time clock operation for time-stamped logging or secure boot timestamping in battery-critical applications.

Can the MC34PF1510A0EP be used with i.MX 6ULL processors?

Yes, the MC34PF1510A0EP is explicitly qualified for i.MX 6ULL processors, as documented in Table 1 of the PF1510 datasheet (orderable part MC34PF1510A6EP for i.MX 6ULL with DDR3L). Its three buck converters supply core (SW1), I/O (SW2), and DDR (SW3) rails, while VREFDDR (0.5–0.9 V) and VSNVS (3.0 V) meet i.MX 6ULL memory and RTC requirements. The unprogrammed OTP allows custom configuration for specific 6ULL memory layouts and power-up timing.

What package type and thermal characteristics does the MC34PF1510A0EP have?

The MC34PF1510A0EP uses a 40-pin QFN package (5.0 mm × 5.0 mm) with exposed thermal pad (EPAD), designed for industrial thermal performance. Key thermal metrics include R_ΘJB = 8.8 °C/W (junction-to-board), R_ΘJMA = 21.4 °C/W at 200 ft/min airflow, and R_ΘJCBOTTOM = 1.4 °C/W. These values are measured per JEDEC JESD51-8 and JESD51-10 standards, confirming suitability for convection-cooled industrial PCBs with standard 4-layer stackups.
