Overview
LD7530/LD7530A 12/5/2007 Green-Mode PWM Controller with Integrated Protections and Adjustable OLP Delay Time REV: 04 General Description 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.
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 Features z z z z z z z z z z z High-Voltage CMOS Process with Excellent ESD protection Very Low Startup Current (<20μA) Current Mode Control Non-audible-noise Green Mode Control UVLO (Under Voltage Lockout) LEB (Leading-Edge Blanking) on CS Pin Internal Slope Compensation OVP (Over Voltag...
