Download the LD5537I1 datasheet PDF.
This datasheet also covers the LD5537B1 variant, as both devices belong to the same green-mode pwm controller family and are provided as variant models within a single manufacturer datasheet.
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.
Key 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. Features.
High-Voltage CMOS Process with Excellent ESD protection.

REV. 00 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.
