LD7523 6/16/2009 Smart Green-Mode PWM Controller with Multiple Protections REV: 00 General Description The LD7523 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 compensation, line compensation, and several protection features. The protection functions include cycle-by-cycle current limit, OVP, OLP, and brownout protection. It provides the users a high efficiency, low external component counts solution for AC/DC power applications. Furthermore, to satisfy various protection requirements, both latch-mode protection and auto-recoverable protection can be easily achieved by configuring LD7523 on different operation modes.
