A4008AS 3CH Power Management IC

The A4008AS is a 3CH power management IC
for applications powered by one Li-Ion battery
or a DC 5V adapter.It integrates three
synchronous buck converters and can provide
high efficiency output at light load and heavy
load operation.The internal compensation
architecture simplifies the application circuit
design.Besides,the independent enable control
makes the designer have the greatest flexibility
to optimize timing for power sequencing
purposes.The A4008AS is available in a 16 pin
QFN 3x3 package.
