LD7532
6/16/2008
Green-Mode PWM Controller with Latch off Protections
REV: 00
General Description
LD7532 is specifically designed for a low cost system by integrating in a SOT-26 package many functions, protections, and EMI-improved solution which usually need a lot of extra components or circuits on a system design. Furthermore, CT pin latch-off function triggered by a high voltage above 3.1V provides power circuit designers to easily deal with protection schemes, such as OVP and OTP, and to minimize component cost and developing time. In order to satisfy different designs, the OVP trig level is adjustable by user adding a Zener diode from VCC pin to CT pin.
