LD7535 General Description
The LD7535 is a low cost, low startup current, current mode PWM controller with green-mode power-saving operation. The integrated functions include the leading-edge blanking of the current sensing, internal slope compensation and the tiny package of SOT-26. It would provide the users a superior AC/DC power application of higher efficiency, low external component counts, and lower cost solution for applications.
In comparing with the previous generations like LD755X, the LD7535 features more or functions for the following characteristics ---
Add OLP (Over Load Protection) function to provide better protection performance for fault conditions like short circuit or over load.
Modify the OVP (Over Voltage Protection) mechanism from the cycle-by-cycle mode to the hiccup mode.
