LD7538 Datasheet | Leadtrend Technology

11/13/2012 Green-Mode PWM Controller with Frequency Swapping and Integrated Protections Rev. 00 General Description The LD7538 is built-in with several functions, protection and EMI-improved solution in a tiny package. It takes less ponents counts or circuit space, especially ideal for those total solutions of low cost. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope pensation. It also Features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit damage occurred under abnormal conditions. Furthermore, the Frequency Swapping...
