DC/DC Converter IC Switching MOSFET

The ROHM PWM type DC/DC Converter for AC/DC provides an optimal system for all products that include an electrical outlet. This IC supports isolated power supply and enables simpler designs of various low power consumption electrical converters. It realizes the high flexibility in power supply design by incorporating a switching MOSFET and with external current detection resistor. This IC can make high efficiency power supply because it has AC low voltage protection function and X capacitor discharge function and operates frequency reduction, minimum ON width adjustment and burst operation at light load.
