NOTES ON EXTERNAL COMPONENTS
If input voltage is high enough, higher efficiency may be obtained by using MOSFET in the driver transistor, in
which case no resistors and condensers are necessary.
Always keep the absolute maximum ratings (V
DS
and V
CE
) since spike voltage higher than output voltage may be
applied to the driver transistor. We recommend that you use transistors with absolute maximum ratings more than
twice of the output setting voltage.
Use capacitor with an allowable voltage which is at least one and a half times as much as the setting output voltage.
Use output voltage setting resistors with resistance much smaller than IC internal resistor (MIN. 2M
). Be care-
ful not to allow larger resistance, which will result in larger error in setting voltage. We recommend resistors up to
several tens of k
.
Select an inductor with small DC resistance and enough permissible current and less tendency to magnetic satura-
tion.
Select a diode of a shot-key type with a faster switching speed. Also pay attention to current capacity.
