MPQ2167BGDE-AEC1-P 개요
A buck converter (also called a step-down switching regulator) is a switch-mode DC-DC converter topology that uses an internal high-side MOSFET, an external or integrated low-side MOSFET, an inductor, and output capacitors to efficiently reduce a higher DC input voltage to a lower regulated output voltage. Within the broader product hierarchy, this part belongs to the synchronous-buck family of voltage regulators, which sits inside the DC-DC switching regulator category, inside the power management IC family, inside the semiconductor category. Synchronous designs replace the traditional Schottky rectifier with a low-side MOSFET, raising light-load efficiency and reducing conduction losses - critical in 3.3 V and 5 V point-of-load applications.
Key features of the MPQ2167BGDE-AEC1-P include 4 A continuous output current, 2.7 V to 6.0 V input range, 0.606 V minimum output, 300 kHz to 2.2 MHz programmable switching frequency, internal power MOSFETs, AEC-Q100 Grade 1 qualification for automotive environments, and a wettable-flank PowerVQFN package that supports automated optical inspection of solder joints. The wide frequency range and small solution footprint suit space-constrained automotive infotainment, ADAS sensor rails, and industrial point-of-load designs.
Typical applications include automotive infotainment and cluster power rails, ADAS camera/sensor power, industrial PLC and factory-automation logic rails, USB-PD and 5 V point-of-load regulation, FPGA/SoC core and I/O supplies, and portable battery-powered equipment. The AEC-Q100 qualification makes it particularly attractive for under-the-hood and body-electronic modules subject to wide temperature swings.
When designing with this device, place the input ceramic capacitors immediately adjacent to the VIN and PGND pins to minimize switching-node ringing, and choose the inductor such that peak-to-peak ripple current stays around 30% of the load. Estimate: at 4 A load, 600 kHz fsw, and 3.3 V VOUT, a 1.5 uH inductor gives roughly 0.45 A ripple. A 2-layer PCB with a continuous ground plane is recommended for thermal dissipation.

일반적인 애플리케이션
MPQ2167BGDE-AEC1-P 적합 용도: 6 애플리케이션s: Automotive Infotainment and Cluster Power Rails, ADAS Camera and Sensor Power, Industrial PLC and Factory Automation Logic Rails, USB-PD and 5 V Point-of-Load Regulation, FPGA / SoC Core and I/O Power, Portable Battery-Powered Equipment.
Automotive Infotainment and Cluster Power Rails
The MPQ2167BGDE-AEC1-P is well suited to 3.3 V and 5 V point-of-load rails inside automotive head units, instrument clusters, and HUD modules. Its 2.7 V to 6.0 V VIN range follows cold-crank and load-dump filtered buses, while 4 A continuous output covers SoC core and peripheral rails. AEC-Q100 Grade 1 qualification and -40 C to +125 C operation support under-dash environments, and the wettable-flank PowerVQFN package enables automated optical inspection on the automotive production line. Programmable switching up to 2.2 MHz shrinks inductors below 1 uH, allowing compact PCB placement behind the display.

ADAS Camera and Sensor Power
Front-facing ADAS cameras and radar sensor modules need low-noise, AEC-Q100-qualified rails at 1.0 V to 3.3 V from a 5 V or 6 V supply. The MPQ2167BGDE-AEC1-P delivers 4 A continuous output with adjustable VOUT down to 0.606 V, supporting image sensor AVDD, MIPI PHY DVDD, and radar transceiver rails. Peak current-mode control yields fast transient response for high-burst sensor loads, while the 300 kHz to 2.2 MHz programmable fsw avoids AM-band interference. The PowerVQFN exposed pad spreads heat to a 4-layer PCB ground pour, sustaining 4 A without a heatsink.
추천
Industrial PLC and Factory Automation Logic Rails
PLC digital I/O modules, industrial Ethernet switches, and motor-control daughtercards require 24 V-to-5 V or 24 V-to-3.3 V isolated or non-isolated rails. When the upstream rail is pre-regulated to 5 V or 6 V, the MPQ2167BGDE-AEC1-P provides a high-efficiency synchronous buck with 4 A continuous output, supporting multi-rail logic and analog front-end supplies. AEC-Q100 qualification, while automotive, also indicates high reliability for industrial environments; the wettable-flank package supports AOI on automated SMT lines used in factory automation assembly.

USB-PD and 5 V Point-of-Load Regulation
USB-PD source and sink applications need a high-efficiency 5 V to lower-voltage rail after the PD controller negotiates a contract. The MPQ2167BGDE-AEC1-P takes the 5 V PD rail directly and steps it down to 1.0 V to 3.3 V at up to 4 A for downstream SoC and memory loads. Programmable switching up to 2.2 MHz keeps the converter above the AM band, important for USB-C accessories that include radios. Internal synchronous MOSFETs simplify the BOM versus an external-FET buck, and the PowerVQFN footprint is small enough for travel adapters and docking stations.
추천
FPGA / SoC Core and I/O Power
Modern FPGAs and SoCs require multiple low-voltage rails - typically 0.85 V core, 1.0 V DDR, 1.8 V auxiliary - sourced from a 3.3 V or 5 V system rail. The MPQ2167BGDE-AEC1-P provides 4 A continuous output adjustable down to 0.606 V, suitable for FPGA core and DDR termination rails. Peak current-mode control provides fast transient response for processor load steps, while the programmable switching frequency from 300 kHz to 2.2 MHz allows the designer to optimize the inductor/capacitor trade-off for each rail. Multiple MPQ2167BGDE-AEC1-P devices can be paralleled for higher current rails.
추천
Portable Battery-Powered Equipment
Portable test equipment, handheld scanners, and battery-powered industrial tablets run from a single-cell Li-ion or Li-polymer cell (2.7 V to 4.2 V) and need 3.3 V or 1.8 V system rails. The MPQ2167BGDE-AEC1-P operates from 2.7 V minimum input, covering the end-of-discharge Li-ion voltage, and produces a regulated rail up to 4 A continuous. Synchronous rectification and a wide switching-frequency range let the designer trade efficiency against solution size for each portable form factor. AEC-Q100 qualification supports industrial and medical portable devices that require extended temperature operation.

설계 노트
Estimated: at VIN = 5 V, VOUT = 3.3 V, IOUT = 4 A, the MPQ2167BGDE-AEC1-P dissipates approximately 6.8 W (assuming 85% efficiency). The 11-pin PowerVQFN thermal pad must be soldered to a continuous ground copper pour; a 4-layer PCB with 1 oz copper on the top layer and 2 oz inner layers typically yields theta_JA around 30-40 C/W. Without a copper pour the junction temperature will exceed 125 C and trigger OTP. Derate to 3 A continuous on a 2-layer board.
Place the input ceramic capacitors (typically 2 x 22 uF X7R 10 V) immediately adjacent to the VIN and PGND pins to minimize the high-di/dt switching loop. Keep the SW node copper area small to reduce radiated EMI, and route the FB trace away from the SW node to avoid noise coupling. The exposed thermal pad requires at least 8 thermal vias (0.3 mm drill, 0.5 mm pitch) to the inner ground plane. Add a 100 nF ceramic bypass capacitor on the BST-to-SW bootstrap node.
Estimated inductor sizing: at fsw = 600 kHz, VOUT = 3.3 V, and 4 A load, a 1.5 uH inductor with low DCR (< 10 mOhm) gives approximately 0.45 A peak-to-peak ripple current (~11% of load). Do not exceed the 6.0 V abs max VIN; add a TVS clamp or input filter for automotive load-dump transients above 6 V. The SS capacitor controls startup time - 10 nF gives about 1 ms rise time, which avoids inrush tripping upstream automotive fuses.
Keep the feedback divider resistor network within 5 mm of the FB pin and AGND pin. Use a Kelvin sense connection from VOUT to the top feedback resistor to avoid IR-drop errors in high-current applications. The PGOOD pull-up resistor (typically 100 kOhm to VOUT) should be placed close to the IC. Route EN and FREQ as low-impedance traces; floating EN below 0.4 V disables the regulator, so use a defined pull-down if left open.
