Product details
Overview
MC34PF1510A4EP 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, three LDOs (including USB_PHY and always-on LDO2P7), DDR reference (VREFDDR), RTC supply (VSNVS), coin-cell charger, and OTP-configurable power sequencing - delivering full-system power for application processors, memory, and peripherals.
For engineers reviewing the MC34PF1510A4EP datasheet, MC34PF1510A4EP pinout, MC34PF1510A4EP application, or MC34PF1510A4EP equivalent, key selection criteria include its −40 °C to 105 °C industrial operating range, I²C programmable DVS on SW1/SW2, 1.0 µA quiescent current in ULP mode, and factory-programmed startup sequence for i.MX 7ULP + LPDDR3.
Technical Context
The MC34PF1510A4EP implements a multi-rail PMIC architecture with independent control logic for each regulator: SW1 and SW2 support dynamic voltage scaling (DVS) across 0.6–1.3875 V (12.5 mV steps) or 1.1–3.3 V (variable steps), while SW3 delivers fixed 1.8–3.3 V outputs without DVS. All bucks operate at 2.0 MHz with internal soft-start and peak efficiency >90%.
Its digital core includes OTP memory storing device-specific configuration (startup timing, voltage levels, sequencing), I²C interface (1.7–3.6 V VDDIO), watchdog timer (80 s period), and dedicated control signals (PWRON, STANDBY, ONKEY, INTB, RESETBMCU) enabling coordinated system-level power state transitions between REGS_DISABLE, Sleep/Low-power, and Standby modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | −40 °C to 105 °C - qualified for industrial embedded applications requiring extended thermal stability |
| Buck Converters | SW1/SW2: 1.0 A, 0.6–1.3875 V (DVS), 1.1–3.3 V (non-DVS); SW3: 1.0 A, 1.8–3.3 V - powers CPU core, SoC I/O, and memory rails |
| LDO Regulators | LDO1/LDO3: 300 mA, 0.75–3.3 V w/ load switch; LDO2: 400 mA, 1.8–3.3 V; LDO2P7: 2.7 V/5 mA always-on; USBPHY: 4.9 V or 3.3 V/60 mA - supports peripheral biasing and USB PHY compliance |
| VREFDDR & VSNVS | VREFDDR: 0.5–0.9 V/10 mA - supplies DDR memory reference; VSNVS: 3.0 V/2.0 mA - powers RTC and secure non-volatile storage |
| Quiescent Current | 1.0 µA in ULP mode (SW1/SW2) - enables ultra-low standby power for battery-operated wearables and IoT edge nodes |
| I²C Interface | Standard-mode (100 kHz) and fast-mode (400 kHz) compatible, VDDIO = 1.7–3.6 V - allows host processor configuration and real-time monitoring |
| OTP Memory | User-programmable start-up/power-down sequences, soft-start timing, and output voltages - eliminates external configuration EEPROM and reduces BOM count |
Pinout & Package
MC34PF1510A4EP uses a 40-pin QFN package (5.0 mm × 5.0 mm, exposed pad), thermally optimized for industrial ambient operation up to 105 °C. The EPAD serves as ground return for buck regulators and requires multiple vias to inner/external ground planes for effective thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN / SW2IN / SW3IN | Buck input supply | Connect to VSYS (2.5–4.5 V); bypassed with 0.1 µF + 4.7 µF capacitors for high-frequency noise suppression |
| SW1FB / SW2FB / SW3FB | Voltage feedback node | Direct connection to output rail near load ensures accurate regulation under dynamic load transients |
| VLDO1 / VLDO2 / VLDO3 | LDO output terminals | Each requires local ceramic bypass (4.7 µF or 10 µF) to ground for stability and transient response |
| VSNVS / USBPHY / LDO2P7 | Always-on or interface-specific rails | VSNVS powers RTC domain; USBPHY supplies USB physical layer; LDO2P7 provides 2.7 V for internal logic - all require mandatory bypassing |
| SCL / SDA / INTB / RESETBMCU | I²C and open-drain signals | Pull-up required (68–100 kΩ to VSNVS or VDDIO ≤3.6 V); supports interrupt-driven power state coordination |
| PWRON / STANDBY / ONKEY / WDI | Processor control inputs | Enable hardware-initiated power transitions (e.g., ONKEY for cold boot, WDI for watchdog reset recovery) |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed OTP | Preconfigured for i.MX 7ULP + LPDDR3 startup sequence, eliminating runtime configuration overhead and ensuring deterministic power-up behavior |
| DVS on SW1/SW2 | Enables real-time voltage scaling of CPU core and GPU rails during performance-state transitions, reducing dynamic power by up to 30% in burst-workload scenarios |
| Ultra-low quiescent current | 1.0 µA in ULP mode (buck regulators) and <1.5 µA in Low-power mode (LDOs) - extends battery life in always-on sensor nodes |
| VIN withstand capability | Withstands DC and transient inputs up to +22 V on VIN pin - protects against adapter surges and hot-plug events in portable systems |
| Integrated coin-cell charger | Supports backup power for RTC via LICELL pin with automatic switchover - maintains timekeeping during main power loss without external circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF1510A2EP | Identical silicon, but programmed for i.MX 7ULP + LPDDR3 with consumer-temp (−40 °C to 85 °C) qualification | Limited to commercial/indoor deployments; lacks 105 °C thermal margin for enclosed industrial enclosures | Select when cost sensitivity outweighs extended temperature requirement and board layout permits derating |
| MC33PF1510A4EP | Same OTP configuration and feature set, but rated for −40 °C to 85 °C ambient and uses MC33 prefix (consumer variant) | Not qualified for industrial ambient; lower thermal resistance spec (RΘJA = 27 °C/W vs. 20.6 °C/W for MC34) | Choose only for space-constrained consumer designs where 105 °C operation is unnecessary |
Compared with MC34PF1510A2EP and MC33PF1510A4EP, the MC34PF1510A4EP uniquely supports sustained operation at 105 °C ambient and delivers superior thermal performance (RΘJA = 20.6 °C/W on six-layer board), making it the sole choice for thermally demanding industrial i.MX 7ULP deployments.

FAQ
What is the primary target processor for the MC34PF1510A4EP?
The MC34PF1510A4EP is factory-programmed for the i.MX 7ULP application processor with LPDDR3 memory interface. Its OTP configuration defines the exact power-up sequence, voltage levels, and timing parameters required by this specific processor-memory combination, ensuring deterministic initialization without runtime software configuration.
Does the MC34PF1510A4EP support dynamic voltage scaling (DVS)?
Yes, the MC34PF1510A4EP supports DVS on SW1 and SW2 buck converters, allowing real-time adjustment of output voltage between 0.6 V and 1.3875 V in 12.5 mV steps. This feature is enabled via OTP programming and controlled through the I²C interface, enabling power optimization during CPU frequency scaling in the i.MX 7ULP.
What is the maximum input voltage the MC34PF1510A4EP can withstand on the VIN pin?
The MC34PF1510A4EP VIN pin withstands transient and DC inputs up to +22 V, as specified in the absolute maximum ratings. This robustness protects the PMIC from voltage spikes during hot-plug events or adapter transients, eliminating the need for external overvoltage protection circuitry in 5 V-powered portable systems.
How does the MC34PF1510A4EP handle RTC power during main supply loss?
The MC34PF1510A4EP provides dedicated RTC power via the VSNVS rail (3.0 V, 2.0 mA) and integrates a coin-cell charger on the LICELL pin. When main power fails, the PMIC automatically switches to coin-cell backup, sustaining RTC operation and secure non-volatile storage - no external diode-or or charging circuitry is required.
Is the MC34PF1510A4EP pin-compatible with other PF1510 variants?
Yes, all PF1510 variants - including MC34PF1510A4EP - share identical 40-pin QFN packaging, pinout, and mechanical footprint. Differences exist only in OTP programming, temperature grade, and part-number prefix/suffix; therefore, PCB layouts designed for any PF1510 variant can accommodate the MC34PF1510A4EP without modification.
