Function
Ground
A logic signal (active low) disables the device (sleep mode operation).
A capacitor connected between this pin and ground determines the soft start time.
When this pin is grounded disables the device (driven by open collector/drain).
An external resistor connected between the unregulated input voltage and this pin and
a capacitor connected from this pin to groundfix the switching frequency. (Line feed
forward is automatically obtained)
Stepdown regulator output
Not regulated DC input voltage
A capacitor connected between this pin and OUT allows to drive the internal VDMOS
E/A output to be used for frequency compensation
Stepdown feedback input. Connecting directly this pin to the output 1.26V is obtained; a
voltage divider is requested for higher output voltages
