Overview
LD7520 11/29/2007 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 compensation, line compensation, 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 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 LD7520 in different operation modes.
The special green-mode control is not only to achieve the low power consumption but also to offer a non-audible-noise operation when the LD7520 is operating under light load or no load condition.
