Start-Up Circuit
General Description
The LD7575B is a current-mode PWM controller with excellent power-saving operation.
It features a highvoltage current source to directly supply the startup current from bulk capacitor and further to provide a lossless startup circuit.
The integrated functions such as the leading-edge blanking of the current sensing, internal slope compensation, and the small package provide the users a high efficiency, minimum external component counts, and low cost solution for AC/DC power applications.
Furthermore, the embedded over voltage protection, over load protection and the special green-mo...
