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 qSI-8200L/8300L Series sTypical Characteristics (Ta=25°C) SI-8201L Rise Characteristics 6 14 12 SI-8203L Rise Characteristics 6 SI-8211L Rise Characteristics 5 5 Output Voltage VO (V) Output Voltage VO (V) 10 8 Output Voltage VO (V) 4 4 RL=12.5Ω IO=0.4A (C.C) 3 3 lO=0A lO=0A RL=34.3Ω IO=0.35A (C.C) 6 4 2 0 0 lO=0 A RL =1 6.7 Ω 5 1 1 0 0 5 10 15 20 5 10 15 20 0 0 IO=0 10 .3A (C.C ) 2 2 15 20 Input Voltage VIN (V) Input Voltage VIN (V) Input Voltage VIN (V) Efficiency Characteristics 80 70 60 50 40 30 20 VIN= 10V 15V 20V 25V 30V 35V 40V Efficiency Characteristics 90 80 70 V =16 VIN V 25 V 40 Efficiency Characteristics 80 70 60 VIN= 15V 25V 35V 45V 55V 20V Efficiency η (%) Efficiency η (%) 30V 35V Efficiency η (%) 60 50 40 30 20 50 40 30 20 10 0 0 10 0 0 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.45 0 0 0.1 0.2 0.3 0.4 0.1 0.2 0.3 0.4 Output Current lO (A) Output Current lO (A) Output Current lO (A) SI-8213L Rise Characteristics 14 12 7 6 SI-8301L Rise Characteristics Output Voltage VO (V) Output Voltage Vo (V) 10 8 6 4 2 5 4 3 2 1 0 lO=0A RL=5.1Ω 0 5 0 0 R IO = 0 lO= L= 0.2 A Ω 43 8A (C .
