DESCRIPTION
The RS2042 is a low startup current, low cost, current mode PWM controller with Green-Power & Burst-mode power-saving operation. The integrated functions such as the leading-edge blanking of the current sensing, internal slope compensation provide the users a high efficiency, low external component counts, and low cost solution for AC/DC power applications.
