Description:
The MPQ4420H 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 2A continuous output current with excellent load and line regulation over a wide input supply range. The MPQ4420H 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 MPQ4420H requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package. .
