LD7551C controller equivalent, green-mode pwm controller.
protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage under the abnormal conditions.
Furthermore, the frequency trem.
The LD7551C integrates low startup current, green-mode power-saving operation, leading-edge blanking of the current sen.
The LD7551C is built-in with several functions, protections and an EMI-improved solution in a SOT-26 package. It takes less components counts or circuit space, especially ideal for those cost sensitive applications.
The LD7551C integrates low startup.
