Current Amplifier
... switched current amplifier designated CA3™ solves this problem. It can provide 3 x 30 A or 1 x 60 A connected in parallel. Maximum output power is 600 VA (3 x 25 A at 8 V). If higher voltage is needed, you can make the connection between two phases (L-L). If you need even higher current, two or more ...

LM78S40 Universal Switching Regulator Subsystem Universal General Description
... LM78S40, to assure its stability. VFD is the forward voltage drop across the internal power diode. It is listed on the data sheet as 1.25V typical, 1.5V maximum. If an external diode is used, then its own forward voltage drop must be used for VFD. VSAT is the voltage across the switch element (outpu ...
