FPDK12SR8004PSS
5.6-14.0Vdc Input, 4A, 0.8-6.6Vdc Output
Sequential
Sequential start-up and shut-down of converters PS1
and PS2 (Fig.D) is enabled by placing an On/Off
circuit between the Vout of PS1 and the REMOTE pin
(pin 3) of PS2.
ｺﾝﾊﾞｰﾀPS1とPS2のｼｰｹﾝｽ起動及び停止(図D)はｵﾝ/ｵﾌ制御回路を
PS1のVoutとPS2のﾘﾓｰﾄ端子(3番ﾋﾟﾝ)の間に配置することで実行され
ます。
A recommended value for R1=13kΩ / R2=4.7kΩ.
各抵抗の推奨値はR1=13kΩ / R2=4.7kΩ
For sequential start-up and shut-down, the PSV type
converters of the FPDK12S Series can be used for
both PS1 and PS2. In that case, R1 and R2 are not
necessary.
ｼｰｹﾝｽ起動及び停止については、PS1及びPS2ともにFPDK12ｼﾘｰｽﾞの
PSVﾀｲﾌﾟも使用可能です。その際は、R1及びR2は不要です。

Simultaneous
Simultaneous start-up and shut-down of converters
PS1 and PS2 (Fig.E), whereby the difference in
output voltage between the converters during turn-on
and turn-off is minimized, is enabled by connecting
the Vout of PS1 to the TRACK pin (pin 4) of PS2.
Note the output voltage setting of PS1 should always
be higher than the output voltage setting of PS2.
電源ｵﾝ及びｵﾌ時のPS1とPS2間の出力電圧の差異を最小化する、こ
れら2つのｺﾝﾊﾞｰﾀの同時起動及び停止は、図Eに示される様に、PS1の
VoutをPS2のTRACK端子(4番ﾋﾟﾝ)に接続することで可能となります。
PS1の設定電圧は常にPS2の設定電圧より高い必要があることに注意
してください。
A recommended value for R1=13kΩ/ R2=4.7kΩ/
R3=10kΩ.
各抵抗の推奨値はR1=13kΩ/ R2=4.7kΩ/ R3=10ｋΩです。
