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 6.). The reference of the error
amplifier is clamped with this voltage (VSS) until it reaches the programmed value. The Device
can always sink current
