Linear Voltage Regulator IC MP2002DD-LF-Z | MPS buck converter 2A 4.5V-18V step-down DC/DC
The MP2002DD-LF-Z is a high-efficiency, step-down (buck) DC/DC converter from Monolithic Power Systems (MPS), designed for compact and power-sensitive applications. This synchronous rectifier operates over a wide input voltage range of 4.5V to 18V, delivering an adjustable output voltage from 0.8V to 16V with a maximum output current of 2A. The device integrates both high-side and low-side MOSFETs, reducing external component count and PCB space. It features a fixed switching frequency of 500kHz, ensuring stable performance while minimizing output ripple. The MP2002DD-LF-Z comes in a DFN-8 (3x3mm) package, making it ideal for space-constrained designs in consumer electronics, industrial systems, and networking equipment.
POL power supply IC MP2002DD-LF-Z Key Features The MP2002DD-LF-Z offers high efficiency (up to 95%) due to its synchronous rectification and low RDS(ON) MOSFETs. It includes soft-start functionality to prevent inrush current, cycle-by-cycle current limiting for overcurrent protection (OCP), and thermal shutdown (TSD) for safe operation. The adjustable output voltage (via external resistors) provides design flexibility, while 100% duty cycle capability ensures stable performance even at low input voltages. The device supports automatic pulse-frequency modulation (PFM) mode at light loads, further improving efficiency. Additionally, its wide input voltage range makes it suitable for battery-powered and industrial applications. Applications This buck converter is widely used in portable electronics (tablets, smart devices), networking hardware (routers, switches), and embedded systems requiring efficient power conversion. It is also ideal for distributed power systems, industrial automation, and automotive infotainment due to its robust performance and reliability. The MP2002DD-LF-Z is commonly employed in FPGA, ASIC, and processor power supplies, where stable voltage regulation is critical. Its compact size and high efficiency make it a preferred choice for IoT devices, medical equipment, and point-of-load (POL) applications. Selection Advantages Compared to similar buck converters, the MP2002DD-LF-Z stands out due to its high integration (built-in MOSFETs), reducing BOM cost and PCB footprint. The wide input voltage range supports diverse power sources, while high efficiency across load conditions extends battery life in portable applications. Its comprehensive protection features (OCP, TSD, soft-start) enhance system reliability, and the small DFN-8 package enables high-density designs. Additionally, MPS’s advanced power management expertise ensures high performance and quality, making this converter a dependable choice for demanding applications.
