LD5532 Datasheet | Leadtrend Technology

Description The LD5532 is built with several functions, audio noise prevention, 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. It includes low startup current, green-mode power-saving operation, leading-edge blanking of the current sense and internal slope pensation. It also features protections of OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit from damage under abnormal conditions. Furthermore, the Frequency Swapping function is also built-in 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.
