General Description

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 operation, leading-edge

blanking of the current sensing and internal slope

compensation. It also 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 EMI filter design by

spending minimum amount of component cost and

developing time.
