LD5536 Datasheet | Leadtrend Technology

Description The LD5536 is built-in with several functions, protection and EMI-improved solution in a tiny package. It takes less ponents-counts and 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 function is to reduce the noise level and thus helps the power circuit designers to easily deal with the EMI filter design by spending minimum amount of ponent cost and developing time.
