Soft Start Operation
(1) Description
When the CTL-1 to CTL-4 pins are driven high (“H” level)
The channel-8 output voltage is soft-started by the capacitor (C
+IN8
) connected to the +IN8 terminal (pin 6).
The capacitor (Cs) connected to the CS terminal (pin 32) starts being charged and the output voltages of channels
1 to 4 and channel 8 are soft-started by the error amplifier in proportion to the CS pin voltage.
