LD5533

LD5533 11/14/2016 Green-Mode PWM Controller with Frequency Swapping and Integrated Protections REV:01 General Description The LD5533 is built with several functions, 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. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. It also features more protections like OPP (Over Power Protection), OCP (Over Current Protection), OSCP (Output Short Circuit 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 component cost and developing time.
