MPS Synchronous Buck Regulator MP4423GQ
MP4423GQ
MP4423GQ—MPS automotive 3 A synchronous buck, 4–30 V in, 0.8–28 V out, fixed 410 kHz, QFN-8 (3 mm×3 mm), 95 % peak efficiency. Integrates 70 mΩ/35 mΩ MOSFETs, 25 µA light-load ECOT, 0.8 µA shutdown. Features cycle-by-cycle current limit, hiccup SCP, OTP, soft-start, PG, –40 °C to +125 °C, AEC-Q100 Grade 1. Ideal for 3 A high-power-density supplies in automotive, industrial, and communication systems.
Founded in Silicon Valley in 1997 and listed on Nasdaq (MPWR) in 2004, Monolithic Power Systems (MPS) is headquartered in San Jose, California. Leveraging its patented BCD process, MPS monolithically integrates high- and low-side MOSFETs, compensation and protection circuits to deliver more than 4,000 compact, high-efficiency power ICs—up to 96 % peak efficiency with micro-second load-transient response and packages as small as 2 mm². The portfolio spans synchronous buck, boost, buck-boost, LED drivers, multiphase controllers and power modules, all qualified to AEC-Q100 Grade 1 (–40 °C to +150 °C, 50 g vibration). MPS devices are in volume production in NVIDIA AI accelerators, Li Auto/VW ADAS, industrial PLCs, telecom base-stations and energy-storage systems, with annual shipments exceeding 1.3 billion units, making MPS a core power-management supplier to the automotive and data-center markets.As a distributor, Mandu Technology offers customers a wide variety of storage-product solutions.
