Product details
Overview
MC34PF1510A2EP 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 devices. 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 MC34PF1510A2EP datasheet, MC34PF1510A2EP pinout, MC34PF1510A2EP application, or MC34PF1510A2EP equivalent, key selection criteria include its −40 °C to 105 °C industrial operating range, I²C programmability, dynamic voltage scaling on SW1/SW2, 1.0 μA quiescent current in ULP mode, and preconfigured startup sequence for i.MX 7ULP + LPDDR3.
Technical Context
The MC34PF1510A2EP implements a multi-rail PMIC architecture with independent control of three buck regulators (SW1–SW3) and three LDOs (LDO1–LDO3), plus dedicated rails for VREFDDR (0.5–0.9 V), VSNVS (3.0 V), and USBPHY (3.3 V or 4.9 V). Its OTP memory stores device-specific power-up/down sequences, voltage settings, and soft-start timing validated for i.MX 7ULP with LPDDR3.
It features a front-end LDO accepting 4.1–6.0 V input (with 22 V transient withstand), supports forced PWM and adaptive variable-frequency operation, and delivers peak efficiency >90% across load conditions. Power states include REGS_DISABLE (Off), Sleep/Low-power, and Standby - all managed via I²C interface and processor control signals (PWRON, STANDBY, ONKEY, WDI).

Pinout & Package
MC34PF1510A2EP uses a 40-pin QFN package (5.0 mm × 5.0 mm, 0.5 mm pitch) with an exposed thermal pad (EPAD) connected to ground for thermal management. Pin functions are defined per NXP's PF1510 datasheet Rev. 4 (2021), with 38 active terminals and two NC pins (33, 34).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN / SW2IN / SW3IN | Buck input supply nodes | Accept VSYS (2.5–4.5 V); require local 0.1 µF + 4.7 µF bypassing to GND for stability and EMI suppression. |
| SW1FB / SW2FB / SW3FB | Voltage feedback inputs | Connect directly to regulated output rail near load to minimize sensing error and improve transient response. |
| VLDO1 / VLDO2 / VLDO3 | LDO output terminals | Each requires dedicated ceramic output capacitor (4.7 µF or 10 µF) to ensure regulation and PSRR performance. |
| VSNVS / USBPHY / LDO2P7 | Dedicated low-noise outputs | VSNVS powers RTC during main power loss; USBPHY supplies USB PHY at 3.3 V or 4.9 V; LDO2P7 is always-on 2.7 V rail. |
| SCL / SDA / INTB / RESETBMCU | I²C and open-drain signals | Require external pull-ups to VDDIO (1.7–3.6 V); INTB and RESETBMCU are active-low, open-drain outputs. |
| PWRON / STANDBY / ONKEY / WDI | Processor control inputs | Enable system-level power state transitions (On/Off/Standby); ONKEY supports mechanical button wake-up; WDI resets watchdog timer. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF1510A4EP | Same silicon, identical pinout and electrical specs; differs only in OTP configuration - programmed for i.MX 7ULP with LPDDR3 (same as A2EP). | No functional difference; both target i.MX 7ULP + LPDDR3. A4EP is alternate preprogrammed variant for same use case. | Select A2EP or A4EP based on availability; both satisfy identical design requirements and qualification data. |
| MPF5020-A0 | NXP's newer dual-core PMIC with higher integration (integrated DC-DC controller, enhanced OTP, wider VIN range up to 20 V), but different pinout and firmware interface. | Targets next-gen i.MX 9x platforms; not drop-in compatible. Requires PCB redesign and firmware adaptation. | Choose MPF5020-A0 only for new designs targeting i.MX 93/95; retain MC34PF1510A2EP for i.MX 7ULP continuity and proven qualification. |
Compared with MC34PF1510A4EP, the MC34PF1510A2EP offers identical functionality and qualification for i.MX 7ULP + LPDDR3, while MPF5020-A0 provides higher integration and future-proofing at the cost of redesign effort and lack of pin compatibility.

FAQ
What is the primary application target for the MC34PF1510A2EP?
The MC34PF1510A2EP is specifically preprogrammed for use with NXP i.MX 7ULP processors paired with LPDDR3 memory in industrial-temperature IoT and wearable applications. Its OTP configuration defines power-up sequencing, voltage levels, and timing parameters validated for this exact processor-memory combination - ensuring reliable boot and stable operation without additional firmware tuning.
Does the MC34PF1510A2EP support dynamic voltage scaling (DVS)?
Yes, the MC34PF1510A2EP supports dynamic voltage scaling on SW1 and SW2 buck converters. This allows real-time adjustment of output voltage under processor control via I²C, enabling power optimization during CPU/GPU frequency scaling. DVS is implemented using 12.5 mV step resolution in the 0.6–1.3875 V range, with programmable ramp rates and soft-start behavior stored in OTP.
What is the maximum input voltage the MC34PF1510A2EP can withstand on the VIN pin?
The MC34PF1510A2EP VIN pin can withstand transient and DC inputs up to +22 V, though normal operating range is 4.1 V to 6.0 V. This robustness protects against surge events in adapter-fed systems. The front-end LDO includes overvoltage protection with a rising threshold of 6.5 V (typical) and 50–250 mV hysteresis to prevent oscillation during recovery.
How does the MC34PF1510A2EP manage ultra-low-power operation?
The MC34PF1510A2EP achieves ultra-low-power operation through multiple mechanisms: 1.0 μA quiescent current in ULP mode for buck regulators, <1.5 μA for LDOs in Low-power mode, and configurable REGS_DISABLE (Off) state. It also supports processor-triggered transitions between Standby, Sleep, and Off modes via PWRON, STANDBY, and ONKEY pins - enabling sub-μA system-level standby in battery-critical applications.
Is the MC34PF1510A2EP pin-compatible with other PF1510 variants like MC34PF1510A1EP or MC34PF1510A3EP?
Yes, all MC34PF1510-x variants share identical 40-pin QFN packaging, pinout, and electrical interface. Differences exist solely in OTP programming - including startup sequence, voltage setpoints, and target processor/memory configuration (e.g., A1EP = default, A3EP = i.MX 6UL with DDR3L). No PCB layout change is required when substituting between MC34PF1510 variants; only firmware initialization may differ.
