EV2183-TL-00A Monolithic Power Systems

EV2183-TL-00A 3A Synchronous Step-down Converter Evaluation Board The Future of Analog IC Technology DESCRIPTION FEATURES Low IQ: 21 A The MP2183 is a monolithic, step-down, switch- 1.2MHz Switching Frequency mode converter with built-in internal power EN for Power Sequencing MOSFETs. It achieves 3A continuous output current from a 2.5V-to-5.5V input voltage with 1% FB Accuracy excellent load and line regulation. The output Wide 2.5V-to-5.5V Operating Input Range voltage can be regulated to as low as 0.6V. Output Adjustable from 0.6V Up to 3A Output Current The Constant-On-Time control scheme 65m and 35m Internal Power MOSFET provides fast transient response and eases loop Switches stabilization. Fault protections include cycle- 100% Duty On bycycle current limiting and thermal shutdown. Output Discharge The MP2183 is available in an ultra-small Vo OVP SOT583 package and requires a minimal External Soft Start Control number of readily available standard external Short-Circuit Protection with Hiccup Mode components. Power Good The MP2183 is ideal for a wide range of Available in a SOT583 Package applications including high performance DSPs, wireless power, portable and mobile devices, APPLICATIONS and other low-power systems.
