Summary

MD1421N is a non-isolated, PWM control stepping down DC to DC converter power IC including main

MOSFET switch and synchronous rectification MOSFET inside. It has maximum 15W ( 5V, 3A ) output

power and high efficiency in wide range. It also has wide input voltage range ( 8 - 40V ) and it is

possible to get 3.3V or 5V output voltage by selecting terminal. Its package is new compact surface

mount type (SSOP-32) and it is possible to design DC to DC converter with fewer external components

and smaller mounting area.
