Note: 1.In Figure 1, part

① is EMS recommended external circuit, part ② is EMI recommended external circuit. Choose according to requirements;

2. V_Cis the voltage to GND from Ctrl, V_Dis the forward conduction voltage drop of D1,I_Cis 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.
