Soft start
When both V
the start-up phase takes place. Otherwise the SS pin is internally shorted to GND. At start-up, a
ramp is generated charging the external capacitor C
initial value for this current is 35µA and charges the capacitor up to 0.5V. After that it becomes
10µA until the final charge value of approximately 4V (see
