LD5537I1 Green-Mode PWM Controller

The LD5537B1/I1 is built-in 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 operati.

LD5537I1 Features

* more protections like OLP (Over Load Protection)、OVP (Over Voltage Protection) and AC BNI / BNO 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 E
