Features
* which include cycle-by-cycle current limit (OCP), fast OCP (FOCP), VCC over voltage protection, OTP, OLP protection. The “CTRL” pin is designed for customers to add external protection functions such as OVP and OTP. The AP3105NX is specially designed for off-line AC-DC power supply, such as LCD moni
Applications
* the system requires external programmable protection function. The CTRL pin has two kinds of modes to trigger the protection: high level trigger and low level trigger. The low threshold voltage is 0.5V and high threshold voltage is 2.5V. When the CTRL pin voltage is lower than 0.5V or higher than 2
