Product details
Overview
MC34PF1510A6EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6ULL application processors with DDR3L memory in industrial-grade portable and IoT 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 regulator, and OTP-configurable power sequencing. It operates across −40 °C to +105 °C and supports dynamic voltage scaling on SW1/SW2 for low-power wearable and embedded monitoring applications.
For engineers reviewing the MC34PF1510A6EP datasheet, MC34PF1510A6EP pinout, MC34PF1510A6EP application, or MC34PF1510A6EP equivalent, this page delivers verified technical context, exact pin functions, confirmed industrial-temperature operation, validated DDR3L-specific OTP configuration, and real-world alternatives for i.MX 6ULL-based designs requiring stable multi-rail power delivery with I²C programmability.
Technical Context
The MC34PF1510A6EP implements a front-end LDO (1500 mA input limit, 22 V transient withstand) feeding VSYS, which powers three synchronous buck regulators with integrated high-side/low-side MOSFETs and digital soft-start. SW1 and SW2 support dynamic voltage scaling (DVS) with 12.5 mV steps in 0.6–1.3875 V range, while SW3 delivers fixed 1.8–3.3 V outputs without DVS.
Its digital core includes OTP memory for user-programmable startup/power-down sequences, I²C interface (1.7–3.6 V VDDIO), watchdog timer (80 s period), and dedicated regulators: LDO2P7 (2.7 V/5 mA always-on), USBPHY (3.3 V or 4.9 V/60 mA), and VSNVS (3.0 V/2.0 mA RTC supply) with coin-cell charging capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp Range | −40 °C to +105 °C - qualified for industrial environments including factory automation and outdoor IoT gateways. |
| Buck Converters | SW1/SW2: 1.0 A, 0.6–1.3875 V (DVS-enabled); SW3: 1.0 A, 1.8–3.3 V (no DVS) - enables core, I/O, and memory rail separation per i.MX 6ULL requirements. |
| LDO Outputs | LDO1/LDO3: 300 mA, 0.75–3.3 V; LDO2: 400 mA, 1.8–3.3 V; LDO2P7: 2.7 V/5 mA always-on - supplies processor I/O, analog cores, and backup domains independently. |
| VREFDDR & VSNVS | VREFDDR: 0.5–0.9 V/10 mA for DDR3L termination; VSNVS: 3.0 V/2.0 mA RTC supply with coin-cell charging - ensures memory interface stability and real-time clock retention. |
| I²C Interface | Compatible with 1.7–3.6 V VDDIO; supports OTP programming and runtime voltage/sequence control - enables firmware-driven power policy adaptation in field-deployed devices. |
| OTP Configuration | Preprogrammed variant A6: optimized for i.MX 6ULL with DDR3L memory timing and voltage sequencing - eliminates external configuration EEPROM and reduces BOM count. |
Pinout & Package
MC34PF1510A6EP uses a 40-pin QFN package (5.0 mm × 5.0 mm, exposed thermal pad), rated for industrial temperature operation and compatible with standard reflow profiles per JEDEC J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN / SW2IN / SW3IN | Buck input supply nodes | Connect to VSYS (2.5–4.5 V) with local 0.1 µF + 4.7 µF bypassing - ensures stable switching node operation under load transients. |
| SW1FB / SW2FB / SW3FB | Voltage feedback inputs | Route directly to respective output rails near load - critical for closed-loop regulation accuracy and transient response of core/I/O/memory rails. |
| VLDO1 / VLDO2 / VLDO3 | LDO output terminals | Each requires dedicated ceramic output capacitor (4.7 µF or 10 µF) - maintains regulation during fast load steps in processor subsystems. |
| VSNVS / USBPHY / LDO2P7 | Always-on or interface regulators | VSNVS powers RTC domain; USBPHY supplies USB PHY at 3.3 V or 4.9 V; LDO2P7 provides 2.7 V bias for internal logic - all require mandatory bypassing per datasheet. |
| SCL / SDA / INTB / RESETBMCU | I²C and open-drain signals | Pull-up to VSNVS or VDDIO (≤3.6 V); INTB signals fault conditions; RESETBMCU asserts active-low reset to processor - enables system-level power coordination. |
| EPAD | Exposed thermal pad | Must be connected to inner/external ground planes via multiple vias - essential for thermal dissipation and EMI reduction in compact industrial PCB layouts. |
Key Features
| Feature | Design Value |
|---|---|
| OTP-programmable power sequencing | User-defined startup/shutdown order and timing for SW1–SW3, LDO1–LDO3, VREFDDR, and VSNVS - eliminates need for external sequencer IC in i.MX 6ULL reference designs. |
| DVS on SW1 and SW2 | Dynamic adjustment of core voltage in 12.5 mV steps during CPU frequency scaling - reduces active power by up to 30% in variable-workload embedded applications. |
| Ultra-low quiescent current | 1.0 µA in ULP mode for buck regulators; <1.5 µA for LDOs in low-power mode - extends battery life in always-on sensor nodes and wearables. |
| VIN transient tolerance | Withstands DC and transient inputs up to +22 V on VIN pin - protects against automotive load-dump surges or adapter overvoltage in portable industrial equipment. |
| DDR3L-optimized VREFDDR | 0.5–0.9 V output with 10 mA drive and tight ±2% accuracy - meets JEDEC DDR3L termination spec for reliable high-speed memory interface on i.MX 6ULL. |

FAQ
What is the primary target processor for the MC34PF1510A6EP?
The MC34PF1510A6EP is specifically preprogrammed for the i.MX 6ULL application processor with DDR3L memory interface. Its OTP configuration includes optimized power-up sequencing, voltage setpoints, and timing parameters aligned to i.MX 6ULL datasheet requirements - distinguishing it from variants intended for i.MX 6UL or i.MX 7ULP processors.
Does the MC34PF1510A6EP support dynamic voltage scaling (DVS)?
Yes, the MC34PF1510A6EP supports DVS on SW1 and SW2 buck converters, enabling real-time adjustment of output voltage in 12.5 mV steps within the 0.6 V to 1.3875 V range. This feature is used during CPU frequency scaling on the i.MX 6ULL to reduce dynamic power consumption without compromising performance or stability.
What is the function of the VREFDDR output on the MC34PF1510A6EP?
The VREFDDR output on the MC34PF1510A6EP provides a precision 0.5 V to 0.9 V reference voltage at up to 10 mA, specifically calibrated for DDR3L memory termination. It meets JEDEC DDR3L specification for VTT tracking and ensures signal integrity on high-speed memory buses in i.MX 6ULL-based systems.
Can the MC34PF1510A6EP operate in industrial temperature environments?
Yes, the MC34PF1510A6EP is rated for −40 °C to +105 °C ambient operation, meeting industrial temperature requirements. This rating is explicitly confirmed in Table 1 of the datasheet for the MC34 prefix variant, enabling use in factory automation, outdoor gateways, and other thermally demanding embedded applications.
Is the MC34PF1510A6EP pin-compatible with other PF1510 variants?
Yes, all PF1510 variants-including MC34PF1510A6EP-share identical 40-pin QFN packaging and pinout. However, OTP configuration differs per variant (e.g., A3 for i.MX 6UL, A6 for i.MX 6ULL), so hardware interchangeability requires verification of startup sequence, voltage defaults, and application-specific timing constraints before substitution.
