【Internal Supply Voltage】

・Function

Regulator input voltage is supplied by VOUT1.

Output voltage is 2.5[V]（TYP）.

No output terminal for internal power supply.

VREF voltage is used to power up internal circuit.

Internal supply rises up at PWM mode (PWM/PFM terminal=H) or CH9 turns ON (XSHDN9=H).
