Preliminary Product Information
1MHz, 800mA Synchronous Buck Converter
With Power Good Detector & LDO
efficiency when selecting an inductor. The inductor is selected to limit the ripple
current to some predetermined value, typically 20~40% of the full load current at the
maximum input voltage. The formula of inductance value is as below:

Power Good Indicator with Adjustable Time Delay
The PG and /PG pin terminal is an open drain output of N-MOS. Connect a resistor
from PG and /PG pin to VCC or OUT1 to create a logic signal. If OUT1 pin is less
than 2.97V (typ.) this pin is pulled to ground. When OUT1 pin is above 2.97V and
with a delay time this pin is open. PG and /PG pin is forced low when in UVLO. The
formula of adjustable delay time is as below :
