Product details
Overview
MC34PF1510A3EPR2 from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 6UL processors with DDR3L memory, delivering three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), VSNVS RTC supply (3.0 V/2.0 mA), DDR reference (VREFDDR, 0.5–0.9 V/10 mA), and I²C programmability. It supports low-power IoT and wearable systems requiring tight voltage sequencing and dynamic voltage scaling.
For engineers reviewing the MC34PF1510A3EPR2 datasheet, MC34PF1510A3EPR2 pinout, MC34PF1510A3EPR2 application, or MC34PF1510A3EPR2 equivalent, key selection criteria include its −40 °C to 105 °C industrial temperature rating, QFN40 5.0 mm × 5.0 mm package with exposed pad, OTP-configured startup sequence for i.MX 6UL+DDR3L, and verified compatibility with USB PHY (4.9 V or 3.3 V) and coin-cell backup charging.
Technical Context
The MC34PF1510A3EPR2 integrates a front-end LDO (1500 mA, up to 6.5 V input, 22 V surge tolerant) feeding VSYS, which powers three synchronous buck regulators with internal digital soft-start and DVS capability on SW1/SW2. Its analog/digital core includes OTP memory for user-defined power-up/down sequences, standby/sleep/off modes, and regulator voltage programming - all controlled via I²C interface with VDDIO support from 1.7 V to 3.6 V.
Regulator control logic implements adaptive variable-frequency and forced PWM quasi-fixed-frequency modes per buck channel, while LDO2P7 provides a dedicated always-on 2.7 V/5.0 mA rail. The device features integrated watchdog timer (80 s period), reset output (RESETBMCU), interrupt signaling (INTB), and thermal protection with junction limit of 125 °C.

FAQ
What is the operating temperature range of the MC34PF1510A3EPR2?
The MC34PF1510A3EPR2 is rated for −40 °C to 105 °C ambient operation, qualifying it for industrial applications such as smart home gateways and ruggedized wearables. This extended range is enabled by its QFN40 package with exposed thermal pad and internal thermal protection that limits junction temperature to 125 °C.
How does the MC34PF1510A3EPR2 support i.MX 6UL with DDR3L memory?
The MC34PF1510A3EPR2 is factory-programmed (OTP) with startup sequencing, voltage levels, and timing parameters specifically validated for i.MX 6UL processors paired with DDR3L memory. It delivers VREFDDR at 0.675 V (DDR3L mid-range) and coordinates power-up of VCORE, VDDIO, and memory rails to meet i.MX 6UL specification requirements.
Does the MC34PF1510A3EPR2 include an integrated USB PHY regulator?
Yes, the MC34PF1510A3EPR2 integrates a dedicated USB_PHY LDO providing either 3.3 V or 4.9 V output at up to 60 mA, with 200 mV dropout at full load and 55–75 dB PSRR. This eliminates the need for an external USB voltage regulator in i.MX 6UL-based designs with USB 2.0 host/device functionality.
Can the MC34PF1510A3EPR2 be used without I²C configuration?
Yes - the MC34PF1510A3EPR2 operates autonomously using its factory-programmed OTP settings for i.MX 6UL + DDR3L. I²C is optional and used only for runtime adjustments (e.g., DVS, mode transitions, status reads). All essential power sequencing and regulation functions execute without host intervention after power-on.
What is the purpose of the LICELL pin on the MC34PF1510A3EPR2?
The LICELL pin on the MC34PF1510A3EPR2 serves as a bidirectional coin-cell interface: it charges a backup battery (e.g., CR1220) during main power availability and draws power from it to sustain VSNVS (3.0 V RTC supply) during system shutdown. This ensures continuous real-time clock operation and SRAM retention without external circuitry.
