Error amplifier

Soft start

When both VCC and VIN are above their turn-ON thresholds (VIN is monitored by the OCH pin)

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 CSS with an internal current generator. The

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 Figure 5.).
