(The following only describes one of the four channels, since all these channels are symmetrical.) 1. Standby Switch (pin 4) The power supply can be turned on or off via pin 4 (Stby). The threshold voltage of pin 4 is set at about 3 VBE (typ.). The power supply current is about 0.01 μA (typ.) in the standby state. VCC ON OFF Power 4 10 kΩ ≈ 2 VBE to Bias fil.
