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) ■ SI-8201L Rise Characteristics Efficiency Characteristics 80 6 lo=0A 60 Efficiency η (%) Output Voltage Vo (V) 5 4 Io=0.4A (C.C) 3 RL=12.5Ω 2 50 40 30 20 1 0 VIN 10V 15V 20V 25V 30V 35V 40V 70 0 5 10 Input Voltage VIN (V) 15 10 0 20 0 0.05 0.10 0.15 0.20 0.25 0.30 0.35 Output Current lo (A) 0.40 0.45 ■ SI-8203L Efficiency Characteristics 14 90 12 80 lo=0A 8 Io=0.35A (C.C) 6 RL=34.3Ω 4 60 50 40 30 2 0 VIN 16V 20V 25V 30V 35V 40V 70 10 Efficiency η (%) Output Voltage Vo (V) Rise Characteristics 20 0 5 10 Input Voltage VIN (V) 15 0 20 0 0.1 0.2 Output Current lo (A) 0.3 0.4 ■ SI-8221L Rise Characteristics Efficiency Characteristics 6 90 VIN 80 lo=0A 70 Io=0.4A (C.C) 4 Efficiency η (%) Output Voltage Vo (V) 5 RL=12.5Ω 3 2 60 VIN=8V 10V 15V 20V 25V 30V 35V 50 40 30 1 0 20 0 5 10 Input Voltage VIN (V) 15 20 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) ■ SI-8211L Rise Characteristics Efficiency Characteristics 6 80 lo=0A 60 4 Efficiency η (%) Output Voltage Vo (V) 5 3 2 RL=16.7Ω 40 30 10 Io=0.3A (C.C) 0 50 20 1 0 VIN 15V 25V 35V 45V 55V 70 5 10 Input Voltage VIN (V) 15 0 20 0 0.1 0.2 Output Current lo (A) 0.3 0.4 ■ SI-8213L Rise Characteristics Efficiency Characteristics 14 80 12 lo=0A 70 10 Efficiency η (%) Output Voltage Vo (V) VIN 22V 30V 38V 48V 55V 90 8 6 4 60 50 40 30 RL=43Ω 2 20 Io=0.28A (C.C) 0 0 5 10 Input Voltage VIN (V) 15 0 20 0 0.1 0.2 Output Current lo (A) 0.3 0.4 ■ SI-8301L Rise Characteristics Efficiency Characteristics 7 90 80 70 5 Io=1A (C.C) 4 RL=5.1Ω 3 2 32 60 50 40 30 1 0 VIN 8V 20V 30V 40V lo=0A Efficiency η (%) Output Voltage Vo (V) 6 20 0 5 10 Input Voltage VIN (V) 15 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) 1.0 1.1
