LD5532 Green-Mode PWM Controller

LD5532 Green-Mode PWM Controller

The LD5532 is built with several functions, audio noise prevention, protection and EMI-improved solution in a tiny package. It takes less components counts or circuit space, especially ideal for those total solutions of low cost. It includes low startup current, green-mode power-saving operation, le.

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 component cost and developing time.
