8-2. ON/OFF control
Note5: Keep Trim pin open when not using adjustable output.
Note6: GND pins (1, 4pin) are connected internally. These two pins should be connected to GND line
Recommended capacitor
C1＝47µF
C2＝22µF - 200µF
C1: It is not necessary when impedance is very low on the input side and the line is connected short
between power supply and the converter with ample width. A product with low ESR such as an
organic semiconductor solid capacitor or a multi layered ceramic capacitor is recommended.
C2: Since output capacitor is placed internally, C2 is not required. However, it may be necessary to
satisfy the electric characteristics such as ripple noise. When C2 is connected to the load side,
noise will be reduced. A multi layered ceramic capacitor is recommended.
By using ON/OFF control feature, the output voltage can be turned on and off without
disconnecting the input. The ON/OFF pin is connected to +Vin pin with 30kΩ resistor internally.
Keep the ON/OFF pin OPEN when not using the ON/OFF feature.
