DC/DC Converters

RoHS

DCDC converters are the power supply that output a fixed voltage efficiently, converting the input voltage. There are three types of DCDC 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 cus to mer 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, au to matically.
