LD7532A Datasheet | Leadtrend Technology

12/17/2008 Green-Mode PWM Controller with Latch off Protections REV: 00 General Description The LD7532A is specifically designed for low cost total-system by integrating many functions, protections, and EMI-improved solution in a SOT-26 package which usually need a lot of extra ponents or circuits on general system designs. Furthermore, the CT pin latch function by injecting a high above 3.1V provides power circuit designers an easy way to deal with designs for protections, such as OVP and OTP, minimizing ponent cost and development time. In order to satisfy different designs, the OVP trig level is adjustable by users adding a Zener diode from VCC pin to CT pin. Typical...
