Output voltage (Vout) can be controlled by attaching an external resistance
RA between the terminal no. 5 (Vout) and the terminal no. 6 (Vset).
Voltage change is expressed by the following formula.
Vout = 0.5769 x [68 x RA / 69.3 + RA)] + 0.75
Voltage: Vout Resistance: kΩ
・ Terminals no. 3 and 8 are internally connected.
・ Remote On/Off voltage
In H level (Vin: 0.6-Vin or open): Output Off
In L level (0-Vin: 2.5V): Output On
・ Remote On/Off current
150µA max.
Recommended resistance range is 100-1000kΩ.
1-3. Characteristics of the out-
put voltage adjustment
Output voltage (Vout) can be varied as shown in the figure

2. Notes on mounting and handling
● The connection diagram 1-1 represents the standard
connection methods for this product.
Recommended reflow soldering
ꢀ Consult us for use with other connection methods to
avoid failure.
● This product does not operate if input/output capacitors
are not connected.
245
225
● Output may not be started up if an electrolytic capacitor
is used for input. Use a low-impedance input capacitor
(laminated ceramic capacitor is recommended).
● For proper start-up of the converter, the start-up time of
the input voltage should be 40ms or less. (The time af-
ter the input voltage becomes 0.5V until it reaches the
specified input voltage range, should be 40ms or less.)
● Output parallel connection cannot be applied.
● Output series connection cannot be applied.
● Output may not be started up in low current application.
● Do not use this product in an overload condition. Doing
so can cause failure.
