Additional Infomation About Product

MP28251 20V, 4A Synchronous Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP28251 is a synchronous, rectified, step- Wide 4.75V-to-20V Operating Input Range down, switch-mode converter with internal 4A Output Current power MOSFETs. It offers a very compact Low R Internal Power MOSFETs DS(ON) solution to achieve a 4A continuous output Programmable Switching Frequency current over a wide input supply range with Programmable EN Delay excellent load and line regulation. The Frequency SYNC from 300kHz to 2MHz MP28251 has synchronous mode operation for External Clock higher efficiency over the output current load Low Power Mode Selectable by an External range. Signal Current-mode operation provides a fast External Soft Start transient response and eases loop stabilization. OCP and Thermal Shutdown Full protection features include over-current Available in a 14-pin QFN23 Package protection and thermal shutdown. APPLICATIONS The MP28251 requires a minimal number of DSL Modems readily-available standard external components Cable Modems and is available in a space saving 2mm3mm Set Top Boxes 14-pin QFN package. All MPS parts are lead-free and adhere to the RoHS directive. For MPS green status, please visit MPS website under Products, Quality Assurance page.
