Product details
Overview
MC34PF1510A7EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors in industrial IoT and wearable systems. It integrates 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), and I²C programmable control. Its −40 °C to 105 °C operating range supports rugged embedded deployments.
For engineers reviewing the MC34PF1510A7EPR2 datasheet, MC34PF1510A7EPR2 pinout, MC34PF1510A7EPR2 application, or MC34PF1510A7EPR2 equivalent, key selection criteria include its OTP-configurable startup sequence, dynamic voltage scaling on SW1/SW2, 1.0 µA quiescent current in ULP mode, and QFN40 5.0 mm × 5.0 mm package with exposed thermal pad.
Technical Context
The MC34PF1510A7EPR2 implements a multi-rail PMIC architecture with independent digital control logic, OTP memory for persistent configuration, and integrated front-end LDO (1500 mA, up to 6.5 V input). Its buck regulators support both forced PWM and adaptive variable-frequency modes, while SW1 and SW2 feature DVS for processor core voltage scaling during performance transitions.
It delivers system-level power sequencing via I²C-controlled state machine, enabling coordinated power-up/down of ARM cores, DDR memory, and peripherals. The device includes dedicated USB_PHY LDO (4.9 V or 3.3 V output), always-on LDO2P7 (2.7 V/5.0 mA), coin cell charger interface (LICELL), and watchdog timer (80 s period) - all validated for i.MX 6UL with LPDDR2 memory support per programming option 7.
