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