IC901 LD7576

The LD7576X series bring high performance, combines with highly integrated functions, protections and EMI-improve solution. It’s an ideal solution for those cost-sensitive system, 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 also consist with more protections of OLP (Over Load Protection), OVP (Over Voltage Protection) and OTP (Over Temperature Protection) to prevent the circuit damage under abnormal conditions.

The LD7576X series are available in DIP-8 and SOP-8 package.
