Monolithic Power Systems, Inc. Voltage Regulators - DC DC Switching Regulators MP2403DN-LF

The MP2403DN-LF is a synchronous buck regulator capable of delivering up to 3A of output current with an input voltage range of 4.6V to 32V. It features integrated high-side and low-side MOSFETs with on-resistances of 150m,Ѷ and 80m,Ѷ, respectively, which contribute to its efficiency of up to 95%. The output voltage is adjustable from 0.80V to 28V, making it suitable for various applications, including distributed power systems and notebook computers. The device includes programmable soft-start functionality to minimize inrush current during startup and operates with a fixed frequency of 250kHz. It also incorporates cycle-by-cycle overcurrent protection and input under-voltage lockout for enhanced reliability. The MP2403DN-LF is housed in a thermally enhanced 8-pin SOIC package, which allows for a compact design with minimal external components. Engineers may find this regulator advantageous for applications requiring efficient voltage regulation with a wide input range and adjustable output.
