Datasheet Summary
Green-Power PWM Controller with Freq. Jittering
Page No. : 1/1
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 pensation provide the users a high efficiency, low external ponent counts, and low cost solution for AC/DC power applications. The special Green-Power function provides off-time modulation to linearly decrease the switching frequency under light-load conditions. And under zero-load conditions, the power supply enters burst-mode to further reduce power consumption by shutting off...
