Introduction

AI Translation

The LD7576X series brings high performance, and combines highly integrated functions, protections and EMI-improve solution. It’s an ideal solution for those cost-sensitive systems, reducing component count and overall system cost. The LD7576X series features near-lossless high voltage startup circuit, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. They are also equipped with protections, such as OLP (Over Load Protection), OVP (Over Voltage Protection) and OTP (Over Temperature Protection), to prevent circuit damage under abnormal conditions. The LD7576X series is available in DIP-8 and SOP-8, SOP-7 packages.
