LD7531A Datasheet | Leadtrend Technology

7/6/2009 Green-Mode PWM Controller with Frequency Trembling and Integrated Protections REV: 00 General Description The LD7531A is built-in with several functions, protection and EMI-improved solution in a SOT-26/ DIP-8 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. And the LD7531A Features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage from the abnormal conditions. Furthermore, the...
