In case Io is less than 10mA, connect a bleeder resistor in parallel to C4.
Use if necessary
Be sure to use this for safety.
A varistor is required to protect against lightning surges and static electricity.
Usage Precautions
When the capacitance of the output smoothing electrolytic capacitor C4 is made large the output may not rise.
100 to 2200µF is recommended. Set the rise time within 10ms.
Set the Vod electrolytic capacitor C3 to 10µF.
Be sure to use the VG terminal voltage within the operating voltage range.
Set the external starting resistor (R1+R3) to 720K. Reducing the resistance value may cause failure during startup.
A built-in overcurrent protection circuit (reset type) prevents damage due to surge currents. Please discontinue
operation if protection circuit is continuously active.
