Product Summary

The DM0265R is a green mode fairchild power switch. The DM0265R is an integrated pulse width modulator (PWM) and sense FET specifically designed for high performance offline switch mode power supplies (SMPS) with minimal external components. The DM0265R is an integrated high voltage power switching regulator which combine an avalanche rugged Sense FET with a current mode PWM control block.
