Product details
Overview
MC34PF4210A1ES from NXP Semiconductors is a 14-channel programmable PMIC optimized for i.MX 8M-based audio/video systems, integrating six buck converters (including SW1A/B/C, SW2, SW3A/B, SW4), six LDOs (VGEN1–VGEN6), a 5.0 V boost regulator (SWBST), coin cell charger, and DDR reference (VREFDDR). It delivers up to 4.5 A on SW1A/B/C in combined mode and supports dynamic voltage scaling for processor core rails.
For engineers reviewing the MC34PF4210A1ES datasheet, MC34PF4210A1ES pinout, MC34PF4210A1ES application, or MC34PF4210A1ES equivalent, this device enables full-system power management for OTT STBs, voice assistants, and A/V receivers - with I²C programmability, OTP-configurable startup sequencing, and industrial-grade −40 °C to 105 °C operation in a 56-pin QFN 8×8 mm wettable flank package.
Technical Context
The MC34PF4210A1ES implements a multi-rail architecture with configurable buck topology: SW1A/B/C supports single/dual-phase or independent operation (0.3–1.875 V, up to 4.5 A); SW2 and SW3A/B deliver 2.5 A and 3.0 A respectively across 0.4–3.3 V; SW4 operates as either 1.0 A buck or DDR termination tracker. All bucks support PFM/PWM/APS modes, programmable soft start, current limit, and OCP fault interrupts.
Control logic centers on an I²C interface (SDA/SCL, 3.6 V tolerant) with OTP memory for persistent configuration, plus dedicated digital signals including open-drain INTB (fault), SDWNB (shutdown warning), RESETBMCU (reset/fault indicator), and STANDBY (mode control). The VSNVS rail provides selectable 1.0/1.1/1.2/1.3/1.5/1.8/3.0 V output at 1.0 mA for SNVS/SRTC in industrial applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | VIN = 2.8 V to 4.5 V - powers entire PMIC from single main supply; UVDET threshold ensures reliable startup above 2.65 V |

Pinout & Package
MC34PF4210A1ES uses a 56-pin WF-QFN (wettable flank) package measuring 8 mm × 8 mm with 0.5 mm pitch and exposed thermal pad (EP). The package supports high-density PCB layouts and enhanced solder joint reliability via side-wettable flanks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1AIN / SW1BIN / SW1CIN | Buck input supply pins | Accept 4.8 V max input for respective buck regulators; require local 4.7 µF + 0.1 µF ceramic decoupling |
| SW1ALX / SW1BLX / SW1CLX / SW2LX / SW3ALX / SW3BLX / SW4LX / SWBSTLX | Buck/boost switch node outputs | Connect to external inductors; high dv/dt nodes requiring tight layout and ground shielding |
| SW1FB / SW1CFB / SW2FB / SW3AFB / SW3BFB / SW4FB / SWBSTFB | Voltage feedback inputs | Sample regulated output; must route separately from power paths and terminate at output capacitor |
| VGEN1–VGEN6 | Programmable LDO outputs | Deliver 100–350 mA at user-defined voltages; require specified ceramic output capacitors (2.2–4.7 µF) |
| VREFDDR / VINREFDDR / VHALF | DDR reference generation | VREFDDR = 0.6–0.9 V output; VINREFDDR and VHALF enable accurate tracking to SW3A for LPDDR4 termination |
| INTB / SDWNB / RESETBMCU | Open-drain status outputs | 3.6 V tolerant; drive external processor interrupts/reset; require pull-up resistors per system voltage |

| SDA / SCL / VDDIO | I²C interface | Standard 3.6 V-tolerant I²C bus; VDDIO powers internal level shifters - bypass with 0.1 µF ceramic |
| LICELL / VSNVS | Coin cell interface | LICELL accepts 1.8–3.3 V coin cell; VSNVS outputs 1.0/1.1/1.2/1.3/1.5/1.8/3.0 V at 1.0 mA for SNVS domain in industrial temp range |
| GNDREF / GNDREF1 / SW1VSSSNS / SW3VSSSNS / EP | Ground references | Dedicated ground returns per regulator group; EP must connect to inner/outer ground planes via multiple vias for thermal and EMI control |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436-AEC1 | Automotive-qualified 4-channel buck (3.5 A each), no integrated LDOs or DDR reference; requires external regulators for full i.MX 8M support | Targets automotive infotainment only; lacks coin cell charging, VSNVS, and OTP sequencing needed for consumer A/V | Select when AEC-Q100 qualification is mandatory and system design accommodates external LDOs and DDR ref |
| TPS6521905RHBR | 6-buck + 6-LDO PMIC for i.MX 8M Mini; identical channel count but lower max current (SW1 = 3 A vs 4.5 A), no coin cell charger, consumer temp only (0–85 °C) | Suitable for cost-sensitive STBs without industrial operating requirements or backup battery support | Choose for non-industrial designs where 3 A core rail current suffices and coin cell backup is unnecessary |
Compared with MPQ4436-AEC1 and TPS6521905RHBR, MC34PF4210A1ES uniquely combines industrial temperature rating, integrated coin cell management, OTP-programmable sequencing, and DDR reference - making it the only drop-in power solution for i.MX 8M-based A/V products requiring field-reliable, battery-backed operation across −40 °C to 105 °C.

FAQ
What is the operating temperature range for MC34PF4210A1ES?
MC34PF4210A1ES is rated for −40 °C to 105 °C ambient operation, qualifying it for industrial audio/video applications. This range is confirmed in Table 4 of the datasheet and distinguishes it from consumer-grade variants like MC32PF4210A4ES (0–85 °C). Thermal protection activates at 130–150 °C to safeguard against sustained overload.
Does MC34PF4210A1ES support DDR memory termination?
Yes, MC34PF4210A1ES provides dedicated DDR support via VREFDDR (0.6–0.9 V, ±1 %) and VINREFDDR/VHALF inputs. SW4 can be configured in DDR termination tracking mode, sourcing 50 % of SW3A output - enabling precise VTT generation for LPDDR4 interfaces in i.MX 8M systems.
How is the startup sequence configured on MC34PF4210A1ES?
MC34PF4210A1ES uses on-chip OTP memory to store startup configuration, including voltage ramp order, timing delays, and enable/disable states for all 14 channels. The A1 variant ships preprogrammed for use with the MCIMX8M-EVK reference design, eliminating need for external configuration memory or I²C initialization at boot.
Can MC34PF4210A1ES operate without a coin cell battery?
Yes, MC34PF4210A1ES can operate without a coin cell: VSNVS may be powered from VIN instead. However, a coin cell is required to maintain SNVS domain functionality (e.g., RTC, secure boot keys) during main supply interruption - and is mandatory for reliable standby mode entry/exit when VIN ≤ 2.85 V and VSNVS is set to 3.0 V.
What package type does MC34PF4210A1ES use, and why is wettable flank important?
MC34PF4210A1ES uses a 56-pin QFN 8×8 mm package with wettable flank (WF) construction. The side-wettable flanks enable automated optical inspection (AOI) of solder joints - critical for high-reliability A/V manufacturing - and improve thermal conduction via the exposed pad (RΘJB = 10 °C/W).
