On the TPS63010 data sheet the Typical Application Circuit schematic on page 1 show VINA, EN, PS and VSEL tied to VIN. However, on page 19 the adjustable output voltage circuit shows these pins floating. They are tied to together but they are not tied to VIN but to a capacitor C3, which then goes to ground. The test circuit on page 16 also shows this arrangement. Tying the pins to VIN makes sense to me; the other two circuits do not. Should the other two circuits show a connection to VIN also and what is C3 for?
