LD7551C - Green-Mode PWM Controller
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 current, green-mode power-saving operation, leadi
LD7551C Features
* protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage under the abnormal conditions. Furthermore, the frequency trembling function is to reduce the noise level and help the power circuit designers for the EMI filter design with minimum component
