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 a flow of 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 metallic 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 operated in specific environments. Verify the operating environment and use the IC within the conditions indicated in the reliability data. 30 SI-8200L/8300L Series Typical Operating Characteristics (Ta=25°C) s SI-8201L Rise Characteristics 6 5 Output Voltage Vo (V) Efficiency Characteristics 80 70 VIN 10V 15V 20V 25V 30V 35V 40V lo=0A 4 Io=0.4A (C.C) 3 RL=12.5Ω 2 1 0 Efficiency η (%) 60 50 40 30 20 10 0 0 5 10 Input Voltage VIN (V) 15 20 0 0.05 0.10 0.15 0.20 0.25 0.30 0.35 Output Current lo (A) 0.40 0.45 s SI-8203L Rise Characteristics 14 12 Output Voltage Vo (V) Efficiency Characteristics 90 80 70 Efficiency η (%) VIN 16V 20V 25V 30V 35V 40V 10 8 6 RL=34.3Ω 4 2 0 0 5 10 Input Voltage VIN (V) 15 20 lo=0A Io=0.35A (C.C) 60 50 40 30 20 0 0 0.1 0.2 Output Current lo (A) 0.3 0.4 s SI-8221L Rise Characteristics 6 5 Output Voltage Vo (V) 4 3 2 1 0 90 VIN Efficiency Characteristics VIN=8V 10V 15V 20V 25V 30V 35V 80 lo=0A Io=0.4A (C.C) 70 Efficiency η (%) 15 20 60 50 40 30 20 RL=12.5Ω 0 5 10 Input Voltage VIN (V) 0 0 0.05 0.1 0.15 0.2 0.25 0.3 Output Current lo (A) 0.35 0.4 0.45 31 SI-8200L/8300L Series SI-8200L/8300L Series Typical Operating Characteristics (Ta=25°C) s SI-8211L Rise Characteristics 6 5 80 70 lo=0A Efficiency η (%) 4 3 2 RL=16.7Ω 1 Io=0.3A (C.C) 0 0 5 10 Input Voltage VIN (V) 15 20 60 50 40 30 20 10 0 0 0.1 0.2 Output Current lo (A) 0.3 0.4 Efficiency Characteristics VIN 15V 25V 35V 45V 55V s SI-8213L Rise Characteristics 14 12 Output Voltage Vo (V) 90 80 Output Voltage Vo (V) Efficiency Characteristics VIN 22V 30V 38V 48V 55V lo=0A 70 10 Efficiency η (%) RL=43Ω 2 Io=0.28A (C.C) 0 0 5 10 Input Voltage VIN (V) 15 20 8 6 4 60 50 40 30 20 0 0 0.1 0.2 Output Current lo (A) 0.3 0.4 s SI-8301L Rise Characteristics 7 6 Output Voltage Vo (V) Efficiency Characteristics 90 80 lo=0A 5 Io=1A (C.C) 4 3 2 1 0 0 5 10 Input Voltage VIN (V) 15 20 RL=5.1Ω Efficiency η (%) 70 60 50 40 30 20 0 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 Output Current lo (A) VIN 8V 20V 30V 40V 1.0 1.1 32
