Product details
Overview
MC34PF1510A2EPR2 from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 7ULP processors with LPDDR3 memory in industrial-temperature 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), VREFDDR (0.5–0.9 V/10 mA), USB_PHY LDO, and OTP-configurable power sequencing - delivering full-system power for application processors, DDR memory, and peripherals.
For engineers reviewing the MC34PF1510A2EPR2 datasheet, MC34PF1510A2EPR2 pinout, MC34PF1510A2EPR2 application, or MC34PF1510A2EPR2 equivalent, this page provides verified technical context, validated pin functions, confirmed industrial-grade thermal specs (−40 °C to 105 °C), exact regulator output ranges, and real-world alternative selection guidance for i.MX 7ULP-based designs.
Technical Context
The MC34PF1510A2EPR2 implements a dedicated front-end LDO (1500 mA, 4.1–6.0 V input, 22 V transient tolerance) feeding VSYS, which powers three synchronous buck regulators with dynamic voltage scaling (SW1/SW2) and fixed-output SW3 (1.8–3.3 V). All bucks support programmable soft-start, current limiting, and dual-mode operation (forced PWM or adaptive variable-frequency).
Its digital core includes I²C interface, OTP memory for startup/power-down sequence configuration, and integrated logic for standby/sleep/off modes. The device features dedicated rails for DDR reference (VREFDDR), RTC backup (VSNVS), coin-cell charging (LICELL), and USB PHY supply - all coordinated via internal state machine without external microcontroller intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.1 V to 6.0 V (VIN), with 22 V DC/transient withstand capability - enables robust USB/adapter input handling without external protection. |
| Buck Converters | SW1 & SW2: 0.6–1.3875 V (12.5 mV steps) or 1.1–3.3 V (variable); SW3: 1.8–3.3 V (100 mV steps); all rated 1.0 A - supports core, I/O, and memory rail requirements of i.MX 7ULP. |
| LDO Outputs | LDO1/LDO3: 0.75–1.5 V or 1.8–3.3 V / 300 mA; LDO2: 1.8–3.3 V / 400 mA; LDO2P7: 2.7 V / 5.0 mA; USBPHY: 3.3 V or 4.9 V / 60 mA - supplies analog cores, interfaces, and PHYs with low-noise regulation. |
| VREFDDR & VSNVS | VREFDDR: 0.5–0.9 V / 10 mA (DDR3/LPDDR3 reference); VSNVS: 3.0 V / 2.0 mA (RTC backup) - meets JEDEC DDR timing and real-time clock retention requirements. |

Pinout & Package
MC34PF1510A2EPR2 is housed in a 40-pin QFN package (5.0 mm × 5.0 mm, 0.5 mm pitch) with an exposed thermal pad (EPAD) connected to GND for enhanced thermal performance. Pin functions are validated per NXP PF1510 datasheet Rev. 4 (March 2021), Table 2 and Figure 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN, SW2IN, SW3IN | Buck converter input supply nodes | Connect to VSYS (3.7 V typical); require local 0.1 µF + 4.7 µF bypassing - ensures stable high-current switching operation. |
| SW1LX, SW2LX, SW3LX | Buck switching nodes | Drive external inductors; must be routed with minimal loop area to reduce EMI and losses - critical for efficiency and thermal management. |
| SW1FB, SW2FB, SW3FB | Voltage feedback inputs | Connect directly to respective output rails near load - enables precise regulation under dynamic load conditions and minimizes PCB trace impedance effects. |
| VSNVS, LICELL, VREFDDR | Dedicated system rails | VSNVS powers RTC domain; LICELL supports coin-cell backup charging; VREFDDR supplies DDR memory reference - each requires specified decoupling per datasheet. |
| SCL, SDA, INTB, RESETBMCU | I²C control and status signals | Enable bidirectional communication and interrupt-driven event handling (e.g., fault reporting, power-state changes) - operate at 1.7–3.6 V logic levels. |
| EPAD (Pin 41) | Thermal and electrical ground return | Mandatory connection to inner/external GND planes via multiple vias - essential for thermal dissipation and noise suppression in buck regulator paths. |
Key Features
| Feature | Design Value |
|---|---|
| OTP-programmable power sequencing | User-defined startup/shutdown order, timing, and soft-start for SW1–SW3, LDO1–LDO3, and VREFDDR - eliminates need for external sequencer in i.MX 7ULP designs. |
| Dynamic Voltage Scaling (DVS) | SW1 and SW2 support real-time voltage adjustment (e.g., CPU core scaling) via I²C - reduces active power by up to 40% during low-load operation. |
| Ultra-low quiescent current | 1.0 µA in ULP mode (buck off, LDOs in low-power state) - extends battery life in always-on IoT endpoints and wearables. |
| Industrial-grade thermal design | RΘJA = 17.8 °C/W (8-layer board), junction limit 125 °C - sustains full 1.0 A buck loads continuously at 105 °C ambient without derating. |
| Integrated DDR3/LPDDR3 support | VREFDDR (0.5–0.9 V, ±2% accuracy) and VSNVS (3.0 V, 2.0 mA) meet JEDEC JESD209-3/4 specifications - enables direct interface with i.MX 7ULP's LPDDR3 controller. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF1510A4EPR2 | Same silicon, OTP-programmed for identical i.MX 7ULP + LPDDR3 use case but with alternate startup timing and DVS settings. | Valid for same target platform; differs only in factory OTP configuration - not software-reprogrammable in-field. | Select when requiring NXP-validated alternate sequencing (e.g., faster SW1 ramp for low-latency wake-up). |
| MPQ4436AGU-AEC1-P | Automotive-qualified 3-buck/3-LDO PMIC (1.2 A bucks, 4.5–36 V input); no OTP, no VREFDDR/VSNVS; I²C only. | Targets automotive infotainment (AEC-Q100 Grade 1); lacks DDR reference, RTC backup, and i.MX-specific sequencing - incompatible with i.MX 7ULP memory interface. | Consider only for non-i.MX designs requiring wider input range and automotive qualification; not a functional substitute for MC34PF1510A2EPR2. |
Compared with MC34PF1510A4EPR2, the MC34PF1510A2EPR2 offers identical hardware functionality but with factory-optimized OTP settings for i.MX 7ULP LPDDR3 timing margins and power-up stability; versus MPQ4436AGU-AEC1-P, it provides DDR-specific rails and programmable sequencing essential for i.MX platforms - making it irreplaceable in its intended application scope.

FAQ
What is the primary target processor for the MC34PF1510A2EPR2?
The MC34PF1510A2EPR2 is factory-programmed for the i.MX 7ULP application processor with LPDDR3 memory interface. Its OTP configuration enforces precise power-up sequencing, VREFDDR voltage accuracy (±2%), and VSNVS timing alignment required by the i.MX 7ULP's memory controller - making it incompatible with non-i.MX 7ULP platforms without reprogramming (not supported in-field).
Does the MC34PF1510A2EPR2 support dynamic voltage scaling (DVS) on all buck converters?
The MC34PF1510A2EPR2 supports DVS only on SW1 and SW2 - enabling real-time voltage adjustment for CPU/GPU cores. SW3 is fixed-output (1.8–3.3 V in 100 mV steps) and does not support DVS. This matches i.MX 7ULP's architecture where SW1/SW2 power scalable domains while SW3 supplies fixed-voltage I/O rails.
What is the maximum input voltage the MC34PF1510A2EPR2 can withstand on the VIN pin?
The MC34PF1510A2EPR2 VIN pin withstands up to +22 V DC or transient input - verified per datasheet Table 4 Absolute Maximum Ratings. This allows direct connection to unregulated 12 V or 24 V supplies with appropriate front-end filtering, eliminating need for external overvoltage protection in industrial power inputs.
How is the VREFDDR output configured for LPDDR3 compliance on the MC34PF1510A2EPR2?
The MC34PF1510A2EPR2 delivers VREFDDR at 0.5–0.9 V with ±2% accuracy and 10 mA drive capability - meeting JEDEC JESD209-3 LPDDR3 specification. Its OTP programming sets VREFDDR to 0.6 V nominal for i.MX 7ULP LPDDR3, with dedicated feedback path and 1.0 µF local decoupling to ensure stability under DDR bus switching noise.
Can the MC34PF1510A2EPR2 operate in industrial temperature range without derating?
Yes - the MC34PF1510A2EPR2 is fully specified from −40 °C to +105 °C ambient (Table 3 Thermal Ratings). Its RΘJA of 17.8 °C/W on an 8-layer board ensures junction temperature remains below 125 °C even at full 1.0 A buck load and 105 °C ambient, with no current or voltage derating required.
