BD9634GU Datasheet, PDF (9/30 Pages) Rohm – Switching Regulator ICs

BD9634GU
【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).
