Soft Start Operation
1. Description
When the CTL, CTL1,2, CTL3, CTL4, and CTL5 terminals are driven high (“H” level) at the same time
The capacitor (C+IN6) connected to the C+IN6 terminal (pin 5) starts charging. When the C+IN6 terminal voltage
falls below 0.9 V (Typ.), the capacitor (Cs) connected to the CS terminal (pin 15) starts charging and the error
amp. provides a soft start by comparing the CH1 to CH5 output voltage to the voltage at the CS terminal.
