Description

General part information

MP2225 Series

The MP2225 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 5A output current with excellent load and line regulation over a wide input supply range. The MP2225 has synchronous mode operation for higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection and thermal shut down. The MP2225 requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package.Wide 4.5V-to-18V Operating Input Range Adjustable Output Voltage as low as 0.6V Low 47mO/18mO RDS(ON) of Internal Power MOSFETs High Efficiency up to 97% Fixed 500kHz Switching Frequency Synchronizes from a 200kHz-to-2MHz External Clock 2.4ms Internal Soft-Start Time 1% Reference Accuracy at Room Temperature Internal Power-save Mode OCP with hiccup mode Available in 8-pin TSOT23
