Leadtrend Technology LD7530

The LD7530/LD7530A are specifically designed for the low total system cost by integrating many functions, protections, and the EMI-improved solution in a tiny SOT-26 package which usually need a lot of extra components or circuits on the general designs.

GENERAL DESCRIPTION

Furthermore, the LD7530/7530A features green mode operation, leading edge blanking time, internal slope compensation and adjustable over load protection (OLP) delay time to minimize the component counts for switching power supply. And to satisfy different designs, 2 versions of OVP levels are implemented as --z z
