MPN： MC34PF3000A1EP ✗ 停產MC34PF3000A1EP 概覽
A PMIC (Power Management Integrated Circuit) is a class of mixed-signal IC that consolidates multiple voltage regulators, supervision circuitry, and power-sequencing logic into one package. Within the broader taxonomy, the MC34PF3000A1EP is an application-specific PMIC in the power management IC family, sitting between discrete regulators and full system power architectures. By collapsing what would otherwise be 11+ discrete switching and linear converters onto one die, it shrinks board area, reduces BOM count, and provides I2C-controlled dynamic voltage scaling for energy-aware SoC operation.
Key features include programmable output voltages, software-controlled sequencing via I2C/SPI, integrated power-good signaling, and a quiescent current of approximately 200 uA. The device supports dynamic voltage scaling (DVS) for the i.MX core, allowing software to lower Vcore during idle states to extend battery life. It also provides fault monitoring on every rail with interrupt generation to the host processor. The exposed thermal pad keeps the 48-QFN package thermally viable for the multi-rail power dissipation profile.
The architecture uses four synchronous buck regulators with internal MOSFETs, one asynchronous boost converter, and six low-dropout linear regulators with individual enable bits. An on-chip state machine handles power-up and power-down sequencing matched to i.MX 6 requirements, while the I2C interface exposes all regulator trim, mode, and status registers for full software control.
Typical applications include i.MX 6 / i.MX 7 Single Board Computers, industrial HMI panels, portable medical devices, infotainment head units, and IoT edge gateways. Designers choose the MC34PF3000A1EP when they need a single-IC power tree that is fully validated against the i.MX reference designs, eliminating the risk of sequencing errors across discrete regulators.
When designing with this PMIC, follow the i.MX 6 hardware reference manual for default rail assignments and decoupling capacitor selection. Always respect the exposed-pad soldering guideline and provide adequate copper area for thermal dissipation - the part is rated for industrial environments but thermal derating still applies at high ambient temperatures.

典型應用
MC34PF3000A1EP 適用於 6 應用s: i.MX 6 Single Board Computer, Industrial HMI / Touch Panel, Portable Medical Device, Automotive Infotainment Head Unit, IoT Edge Gateway, Smart Home Control Hub.
i.MX 6 Single Board Computer
The MC34PF3000A1EP is the canonical NXP-recommended PMIC for i.MX 6 / i.MX 7 single board computers, delivering all 11 rails required by the SoC, DDR memory, and peripherals from a single 2.8-5.5 V input. Its pre-programmed register defaults match the i.MX 6 hardware reference manual boot sequence, eliminating firmware bring-up time. The integrated I2C control enables dynamic voltage scaling on Vcore to reduce idle power by 30-50% compared to fixed-voltage designs. According to the NXP PF3000 datasheet, designers using the NXP SABRE reference board can drop the part onto any compatible layout and inherit validated timing and fault behavior.

Industrial HMI / Touch Panel
Industrial human-machine interface panels based on i.MX 6 or i.MX 7 use the MC34PF3000A1EP to consolidate their entire power tree into one industrial-grade IC rated -40 C to +105 C. Its 11 integrated regulators replace what would otherwise be a dozen-plus discrete switching and linear converters, dramatically reducing PCB area in space-constrained panel designs. The PMIC's per-rail power-good outputs and fault interrupt support the deterministic reset behavior required by IEC 61131-2 compliant industrial controllers. The exposed-pad 48-QFN package provides sufficient thermal headroom for the multi-rail dissipation profile in fanless sealed enclosures.
推薦
Portable Medical Device
Battery-powered medical devices such as patient monitors, infusion pumps, and portable diagnostic systems leverage the MC34PF3000A1EP's single-cell Li-ion input range (2.8-4.2 V) and dynamic voltage scaling to maximize runtime. The 200 uA quiescent current and software-controlled sequencing support the strict deterministic power-up required by FDA IEC 62304 software classification workflows. According to NXP application notes, the integrated power-good tree simplifies the safety documentation required for fault detection on each patient-facing rail. The 48-QFN exposed-pad package keeps the device thermally viable inside sealed plastic enclosures typical of handheld medical equipment.

Automotive Infotainment Head Unit
While the MC34PF3000A1EP itself is industrial grade, the same 48-QFN footprint supports the automotive-qualified MC33PF3000A5ES variant for infotainment head units, instrument clusters, and rear-seat entertainment systems. The PMIC's pre-programmed i.MX 6 rail map matches the automotive boot sequence requirements of MOST and Ethernet AVB networks. Designers can prototype with the MC34PF3000A1EP and migrate to the AEC-Q100 qualified sibling for production without changing the PCB layout. Per NXP's reference design documentation, this approach is standard practice for tier-1 automotive electronics developers.
推薦
IoT Edge Gateway
IoT edge gateways running Linux on i.MX 6 or i.MX 7 use the MC34PF3000A1EP to provide software-managed power states across Wi-Fi, BLE, LoRa, and cellular modem peripherals. The I2C-controlled LDOs can be selectively disabled to power down radios during sleep, with wake-up driven by the host SoC's GPIO interrupt tree. According to the PF3000 datasheet, the buck converters' light-load efficiency exceeds 85% at 10 mA, preserving battery life in solar or battery-backed edge deployments. The industrial -40 to +105 C rating supports outdoor enclosure operation.
推薦
Smart Home Control Hub
Smart home hubs and Zigbee/Z-Wave Matter controllers built on i.MX 7 use the MC34PF3000A1EP as a single-IC power solution, replacing 10+ discrete regulators and shrinking the hub's PCB to fit behind a light switch or inside a wall outlet. The integrated 4 buck + 1 boost + 6 LDO topology covers the SoC rails, radio PA supply, and peripheral sensors simultaneously. According to NXP's reference designs, the PMIC's hardware sequencing ensures deterministic radio bring-up, which is critical for Matter commissioning flows that require predictable timing.

設計說明
The 48-QFN exposed pad is the primary thermal dissipation path. Per NXP's PF3000 hardware guidelines, the PCB land pattern must include a copper pour of at least 25 mm x 25 mm connected to the exposed pad with at least 9 thermal vias (0.3 mm drill, 0.5 mm pitch). Without adequate copper, junction temperature can exceed 125 C at full load across all 11 rails in a sealed industrial enclosure.
Place input bulk capacitors (22 uF X5R minimum) within 5 mm of the VIN pin, and each buck converter's output capacitors within 3 mm of their respective SW node. Keep the SW traces short and avoid routing them parallel to sensitive analog feedback traces - the buck switching edges can couple into the LDO feedback loops and degrade ripple performance by 10-20 mV.
Do not skip the I2C pull-up resistors on SCL/SDA - the PMIC's internal pull-ups are weak (typically 50 kohm) and will not meet the I2C fast-mode timing budget on long bus runs. Use external 2.2 kohm pull-ups to the host rail and verify with an oscilloscope that the rise time on SDA stays below 300 ns for 400 kHz operation.
When designing for dynamic voltage scaling on the i.MX 6 core buck, slew Vcore at no more than 1 mV/us. The PF3000's hardware sequencer enforces this internally, but if the host firmware attempts faster transitions via direct I2C writes, the core voltage can briefly undershoot and trigger a brown-out reset. Refer to the i.MX 6 hardware reference manual for the validated DVS timing parameters.
合規資訊
RoHS and REACH compliant per NXP product page. The MC34PF3000A1EP itself is NOT AEC-Q100 qualified - choose the MC33PF3000A5ES sibling for automotive applications requiring AEC-Q100 grade 1 or 2.
