2 / 2 page 63 ICs SI-8000S Series ■External Dimensions (TO220F-5) (Unit : mm) ■Block Diagram ■Typical Connection Diagram ■Ta-PD Characteristics The efficiency depends on the input voltage and the output current. Therefore, obtain the value from the efficiency graph and substi- tute the percentage in the formula above. VO : Output voltage VIN : Input voltage IO : Output current ηx: Efficiency (%) VF : Diode D1 forward voltage 0.5V(RK46) Thermal design for D1 must be considered separately.
