Description

General Description

The LD7575 is a current-mode PWM controller with excellent power-saving operation.

It features a high-voltage 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 compensaton, 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-mode control provide the solution for users to design a high performance power

circuit easily.

The LD7575 is offered in SOP-8 package.
