Smart Green-Mode PWM Controller with Multiple Protections
Spec. 02a
General Description
The LD7520 is a low startup current, current mode PWM controller with green-mode power-saving operation. The SOP-8/DIP-8 package integrated functions such as the leading- edge blanking of the current sensing, internal slope pensation, line pensation, and several protection Features
. The protection functions include cycle-by-cycle current limit, OVP, OTP, and OLP. It provides the users a high efficiency, low external ponent counts solution for AC/DC power applications.
Furthermore, to satisfy various protection requirements, both latch-mode protection and auto-recoverable...
