LD7535/LD7535A 12/11/2007 Green-Mode PWM Controller with Integrated Protections Rev. 01c General


The LD7535/LD7535A are low cost, low startup current, current mode PWM controllers with green-mode powersaving operation. The integrated functions include the


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 Programmable Switching Frequency Internal Slope Compensation OVP (Over Voltage Protection) on Vcc Pin OLP (Over Load Protection) 300mA Driving Capability leading-edge blanking of the current sensing, internal slope compensation and the tiny package of SOT-26. They provide the users a superior AC/DC power application of higher efficiency, low external component counts, and lower cost solution. Furthermore, LD7535/LD7535A features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to eliminate the external protection circuits. And to satisfy different designs, 2 versions of OVP levels are implemented as --z z Applications z z z LD7535 --- 28.0V ± 1.5V. LD7535A --- 21.0V ± 1.5V.
