The condition where the peak current is maximized is when the input voltage is the maximum voltage VIN (Max): 380 V, the maximum load current Io (Max): 0.175 A, and the switching frequency is 106 kHz at the minimum. The peak current IP of the coil is given by the following formula. [mA] Select a coil with an rated current of 0.37 A or more.

Consider the derating and select 600 V diode. The condition where the effective current of the diode is maximized is when the input voltage is the maximum voltage VIN (Max): 380 V, the maximum load current Io (Max): 0.175 A, and the switching frequency is 94 kHz at the minimum.

User's Guide Design Overview - Continued 4 Capacitor Selection 4.1 Input Capacitor: C1 The input capacitor is determined by input voltage VI and output power POUT. As a guide, for an input voltage of 90 to 264 Vac, 2 x POUT [W] F. For 176 to 264 Vac, set 1 x POUT [W] F. Since the output power POUT = 2.63 W, 4.7 F / 400 V is selected with a guidline of 5.38 F. 4.2 VCC Capacitor: C3 The VCC capacitor C3 is required for stable operation of the device and stable feedback of the output voltage. A withstand voltage of 25 V or more is required, and 1.0 F to 4.7 F is recommended. 1 F / 50 V is selected. 4.3 Output Capacitor: C2, C4 For the output capacitor, select output voltage VO of 25 V or more in consideration of derating. For C2 electrolytic capacitors, capacitance, impedance and rated ripple current must be taken into consideration. The output ripple voltage is a composite waveform generated by electrostatic capacity: COUT, impedance: ESR when the ripple component of inductor current: IL flows into the output capacitor and is expressed by the following formula. The inductor ripple current is [A] For this EVK, we use electrostatic capacity: 220 F, ESR: 0.075 , and the design value of output ripple voltage is less than 100 mV. [mV] Next, check whether the ripple current of the capacitor satisfies the rated ripple current.

C8 has added a 0.1 F ceramic capacitor to reduce switching noise. 5. Resistor Selection 5.1 Bleeder Resister: R1 Because it is indirectly fed back to the output voltage, the output voltage increases at light load. This board uses bleeder resistance for its improvement. Reducing the resistance value improves the rise in the output voltage of the light load, but increases the power loss. 10 k / 0.1 W is used.
