Product details
Overview
MC34PF1510A1EP from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 6UL/6ULL/7ULP application processors in industrial-grade portable and IoT systems. It integrates three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), DDR reference (VREFDDR), RTC supply (VSNVS), coin-cell charger, and I²C-configurable OTP memory. It delivers full-system power to processor cores, memory, USB PHY, and peripherals in smart wearables and embedded monitoring devices.
For engineers reviewing the MC34PF1510A1EP datasheet, MC34PF1510A1EP pinout, MC34PF1510A1EP application, or MC34PF1510A1EP equivalent, key selection considerations include its −40 °C to 105 °C industrial temperature rating, 40-pin QFN package with exposed thermal pad, programmable DVS on SW1/SW2, 1.0 µA quiescent current in ULP mode, and preconfigured startup sequence for i.MX 6UL/6ULL platforms.
Technical Context
The MC34PF1510A1EP implements a multi-rail PMIC architecture with independent digital control logic, OTP-programmable sequencing, and dual-mode operation (normal/low-power). Its front-end LDO accepts 4.1–6.0 V input and withstands up to +22 V transients, feeding VSYS to all internal regulators.
SW1 and SW2 support dynamic voltage scaling across 0.6–1.3875 V (12.5 mV steps) or 1.1–3.3 V (variable steps); SW3 provides fixed 1.8–3.3 V outputs without DVS. All bucks operate at 2.0 MHz with internal soft-start, peak efficiency >90%, and RDS(on) of 200 mΩ (P-FET) / 150 mΩ (N-FET).

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF1510A1EP | Consumer-grade variant rated for −40 °C to 85 °C; identical electrical specs and pinout | Targeted for cost-sensitive consumer wearables, not industrial deployments | Select MC33PF1510A1EP only when ambient temperature remains ≤85 °C and lifecycle requirements are less stringent |
| MPF5020-A0 | NXP's newer dual-core PMIC with integrated DC-DC controllers, higher integration, and enhanced safety features (ASIL-B ready) | Designed for automotive infotainment and ADAS; requires different layout and firmware adaptation | Choose MPF5020-A0 for next-gen designs requiring functional safety or higher integration; not drop-in compatible |

FAQ
What is the operating temperature range of the MC34PF1510A1EP?
The MC34PF1510A1EP is rated for an industrial ambient operating temperature range of −40 °C to 105 °C, validated per JEDEC JESD22-A104 and qualified for continuous operation in demanding environments such as factory automation and outdoor IoT gateways. This exceeds the −40 °C to 85 °C rating of the consumer-grade MC33PF1510A1EP variant.
Does the MC34PF1510A1EP support dynamic voltage scaling (DVS)?
Yes, the MC34PF1510A1EP supports DVS on buck converters SW1 and SW2, enabling programmable output voltage adjustment in 12.5 mV steps across 0.6 V to 1.3875 V. This feature allows real-time core voltage tuning synchronized with i.MX processor frequency changes, reducing dynamic power consumption during variable-workload operation.
How is the MC34PF1510A1EP configured for different i.MX processors?
The MC34PF1510A1EP uses one-time programmable (OTP) memory to store device-specific configurations including startup sequence, regulator voltages, soft-start timing, and power-down behavior. The "A1" suffix denotes the default configuration optimized for i.MX 6UL and i.MX 6ULL processors with DDR3L memory, preloaded at manufacture and not field-reprogrammable.
What is the purpose of the VSNVS and LICELL pins on the MC34PF1510A1EP?
VSNVS provides a regulated 3.0 V, 2.0 mA always-on supply for real-time clock (RTC) circuits, while LICELL serves as a bidirectional coin-cell interface that charges the backup battery from VSYS and discharges to maintain VSNVS during main power loss. Together, they ensure uninterrupted timekeeping and state retention across power cycles.
Can the MC34PF1510A1EP be used with i.MX 7ULP processors?
Yes, the MC34PF1510A1EP is compatible with i.MX 7ULP processors, though its A1 configuration is optimized for i.MX 6UL/6ULL. For i.MX 7ULP with LPDDR3, NXP recommends MC34PF1510A2EP or A4EP variants, which include OTP settings for LPDDR3 VREFDDR calibration and specific power sequencing - the A1EP may require firmware-level voltage adjustments for optimal LPDDR3 operation.
