LD7535B
3/10/2008
Green-Mode PWM Controller with Integrated Protections
Rev.01a
General Description
The LD7535B 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 LD7535B features more protections or functions for the following characteristics ---
z Add OLP (Over Load Protection) function to provide better protection performance for fault conditions like short circuit or over load.
