Product details
Overview
MC34PF3001A6EP from NXP Semiconductors is a fixed-configuration Power Management IC (PMIC) designed specifically for i.MX 6UL processors with LPDDR2 memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs including VCC_SD and V33, and integrated coin-cell charging for RTC backup. It operates across −40 °C to +105 °C and supports I²C programmability for dynamic voltage scaling in industrial embedded systems.
For engineers reviewing the MC34PF3001A6EP datasheet, MC34PF3001A6EP pinout, MC34PF3001A6EP application, or MC34PF3001A6EP equivalent, this page provides verified regulator output voltages, OTP-programmed startup sequence (SW1_SEQ=3, SW2_SEQ=3, SW3_SEQ=3), thermal and fault protection features, and confirmed compatibility with i.MX 6UL-based industrial control and medical monitoring platforms.
Technical Context
The MC34PF3001A6EP implements a fixed OTP-programmed power tree optimized for i.MX 6UL with LPDDR2: SW1 delivers 1.4 V at 2.75 A for core logic, SW2 supplies 3.3 V at 1.25 A for I/O domains, and SW3 provides 1.2 V at 1.5 A for DDR termination. All buck regulators support APS/PWM/PFM modes and share a trimmed 16 MHz clock for switching frequency stability.
Its control architecture integrates dedicated logic signals-PWRON (level-sensitive turn-on), RESETBMCU (2 ms post-startup deassertion), INTB (open-drain fault interrupt), and SD_VSEL (dual-range VCC_SD selection)-alongside I²C register access for runtime voltage adjustment, while VSNVS provides 3.0 V/1.0 mA always-on supply with coin-cell charging capability.

FAQ
What is the primary target processor for MC34PF3001A6EP?
MC34PF3001A6EP is specifically configured for the i.MX 6UL processor with LPDDR2 memory, as indicated by its A6 OTP programming code. Its fixed startup sequence (SW1_SEQ=3, SW2_SEQ=3, SW3_SEQ=3), default voltages (SW1=1.4 V, SW2=3.3 V, SW3=1.2 V), and VCC_SD configuration align exclusively with i.MX 6UL LPDDR2 reference designs per NXP PF3001 Rev. 5.1 datasheet Table 4.
Does MC34PF3001A6EP support dynamic voltage scaling (DVS)?
Yes, MC34PF3001A6EP supports dynamic voltage scaling via I²C register writes to SWxVOLT[4:0] fields, enabling real-time adjustment of buck regulator outputs during operation. DVS ramp rate is factory-trimmed to 6.25 mV/μs (PU CONFIG, SWDVS_CLK) for controlled transitions, preserving i.MX 6UL core stability during frequency scaling events.
What is the function of the SD_VSEL pin on MC34PF3001A6EP?
The SD_VSEL pin (Pin 2) on MC34PF3001A6EP selects the output voltage range of the VCC_SD regulator: logic HIGH configures 1.80–1.85 V for SDIO 1.8 V mode, while logic LOW configures 2.85–3.30 V for 3.3 V SD card operation. This hardware-selectable feature ensures JEDEC-compliant interface voltage matching without firmware intervention.
Can MC34PF3001A6EP operate with a 5.0 V input supply?
Yes, MC34PF3001A6EP supports 5.0 V input via the VPWR pin when used with an external PMOS pass FET (e.g., FDMA908PZ) and LDOG gate drive. The internal front-end LDO regulates VPWR down to ≤4.5 V for safe operation of internal regulators, as specified in Section 8.3.5 of the PF3001 datasheet.
What is the purpose of the LICELL pin on MC34PF3001A6EP?
The LICELL pin (Pin 36) on MC34PF3001A6EP provides bidirectional coin-cell interface functionality: it charges a CR2032 battery during main power availability and automatically switches to coin-cell backup for the VSNVS rail (3.0 V/1.0 mA) during main power loss, ensuring continuous RTC operation and secure non-volatile storage retention in industrial and medical applications.
