Thus, obtain the value from the efficiency graph and substitute the percentage in the formula above. ■Caution 1. A low-impedance capacitor suitable for switching applications must be used for the external capacitor and must be connected as close to the IC as possible in order to assure low ripple voltage and stable switching operation. 2. The SI-8200L and 8300L series do not have a built-in overcurrent protection circuit. Thus, avoid short-circuit conditions that may cause an overcurrent. 3. The SI-8300L series may not start up if the input voltage rises too rapidly. Do not use the SI-8300L series in applications where the input terminal, pin6, is opened and closed directly in a state where the input voltage is already applied. 4. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits. 5. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit. 6. Since the SI-8200L and 8300L series have an open-package construction, they can only be used in specific environments. Verify the operating environment and use the IC within the conditions indicated in the reliability data. 94 ●SI-8200L/8300L Series ■Typical Characteristics (Ta=25°C) SI-8201L SI-8203L 6 12 2 5 10 15 0 0 20 10 Efficiency Characteristics 0 0 20 40 30 10 15 20 Efficiency Characteristics 80 20V V =16 VIN V 25 80 70 Efficiency η (%) VIN= 10V 15V 20V 25V 30V 35V 40V 5 Input Voltage VIN (V) Efficiency Characteristics 90 50 15 Input Voltage VIN (V) 80 60 1 5 Input Voltage VIN (V) 70 2 ) 4 3 (C.C 6 4 .3A 8 IO=0 1 0 0 Output Voltage VO (V) lO=0A 10 70 60 V 40 60 30V Efficiency η (%) RL=12.5Ω 3 2 IO=0.4A (C.C) 4 5 lO=0A RL=34.3Ω IO=0.35A (C.C) Output Voltage VO (V) 5 Output Voltage VO (V) Rise Characteristics 14 6 Efficiency η (%) SI-8211L Rise Characteristics lO=0 A RL =1 6.7 Ω Rise Characteristics 35V 50 40 15V 25V 35V 45V VIN= 50 55V 40 30 30 20 20 10 20 10 0 0 0 0 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.45 0.1 0.2 Output Current lO (A) SI-8213L 8 6 C) (C . 0 0 R 5 5 3 2 8A 1 0 10 15 20 0 Efficiency Characteristics 10 15 20 Efficiency Characteristics 90 80 V 22 V 30 V 38 8V 4 80 N= 70 V 55 60 Efficiency η (%) VI Efficiency η (%) 5 Input Voltage VIN (V) 90 50 40 30 V =8 VIN V 20 30V V 40 60 50 40 30 20 0 0 0.4 RL=5.1Ω 4 Input Voltage VIN (V) 70 0.3 0.2 Ω 43 L= 0.2 Output Current lO (A) IO=1A (C.C) 10 A 0.1 lO=0A 6 Output Voltage Vo (V) 12 IO = Output Voltage VO (V) 7 0 lO= 0 0 Rise Characteristics 14 2 0.4 SI-8301L Rise Characteristics 4 0.3 Output Current lO (A) 20 0.1 0.2 0.3 Output Current lO (A) 0.4 00 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 Output Current lO (A) 95
