:Efficiency (%)
The efficiency depends on the input
voltage and the output current. Thus,
obtain the value from the efficiency

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 L
IN
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.
