GENERAL DESCRIPTION
The A4001C is a 3-CH power management IC
for applications powered by one Li-Ion battery
or a DC 5V adapter. It integrates three
synchronous buck regulators 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 A4001C is available
in a 24 pin QFN 4x4 package
