BOOT  
Internal bias supply output for bypassing. Connect 2.2-µF, 16-V bypass  
capacitor from this pin to AGND. Do not connect external loading to this  
pin. Never short this pin to ground during operation.

Connect a resistor RT from this pin to AGND to program switching  
frequency. Leave floating for 400-kHz default switching frequency.

Open drain output for power-good flag. Use a 10-kΩto 100-kΩpullup  
resistor to logic rail or other DC voltage no higher than 12 V.

PGOOD  
Enable input to regulator. High = On, Low = Off. Can be connected to VIN.  
Do not float. Adjust the input undervoltage lockout with two resistors. The  
internal oscillator can be synchronized to an external clock by coupling a  
positive pulse into this pin through a small coupling capacitor. See 8.3.4  
for details.
