LD7750H规格书详情
描述 Description
The LD7750H integrates several functions of protections, and EMI-improved solution in a SOP-8/or DIP-8 package to minimize the component counts and the circuit space.The device provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation.Also, the LD7750H features more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and OTP (Over Temperature Protection) to prevent the circuit being damaged under the abnormal conditions.The LD7750H features built-in latch function for OVP on Vcc pin and OLP.Furthermore, the LD7750H features frequency swapping to depress radiation noise, providing an excellent solution for EMI filter design.
