LD7523GS PDF – Smart Green-Mode PWM Controller, SOP 8

A current mode PWM (Pulse-Width Modulation) controller is a type of electronic control circuit used in various applications, especially in power electronics and switch-mode power supplies (SMPS). This controller regulates the output voltage or current by adjusting the duty cycle of a PWM signal based on the feedback from the load current.

The LD7523GS 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.
