In Figure 1, part ① is EMS recommended external circuit, part ② is EMI recommended external circuit. Choose according to requirements; 2. VC is the voltage to GND from Ctrl, VD is the forward conduction voltage drop of D1,IC is the current through Ctrl pin which is normally 5-10mA, the external circuit of Ctrl is as shown in figure1- ; ③ 3. If there is no recommended parameters, the model no require the external component. EMC RECOMMENDED CIRCUIT PCB LAYOUT DUAL SINGLE (Figure 2) Note: The pad space between input and output GND (CY) must ≥2mm. |
