  Products > DC/DC Converter
 
         The UNI’s DC/DC converters are the power supply that output a fixed voltage efficiently, converting the input voltage. There are  three  types of DC/DC converters, step-up DC/DC converters, step-down DC/DC converters, and step-up/down DC/DC converters, Multi channel DC/DC converters. They respond to customer needs lining up four  types of control. PWM  controlled  types are highly efficient and excel  in  the  ripple and  the noise of output voltage. PFM controlled  types consume only a  little power even  if operated all  the  time, especially when  lightly loaded. PWM  /PFM switchable  types work at PFM control when  loaded  lightly and switch  to PWM control when loaded heavily, automatically.
