Leadtrend Technology LD7552D
The LD7552D are specifically designed for the low total system cost by integrating many functions, protections, and the EMI-improved solution in a SOP-8 package which usually need a lot of extra components or circuits on the general designs. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. And the LD7552D features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage from the abnormal conditions.| Part No. | LD7552D |
