General Description

The CR6842 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.
