efficiency over a wide load current range. The Power
Save mode can be disabled, forcing the converter to
operate at a fixed switching frequency. The maximum
average current in the switches is limited to a typical
value of 4A. The output voltage is programmable
using an external resistor divider, or is fixed internally
on the chip. The converter can be disabled to
minimize battery drain. During shutdown, the load is
disconnected
from
the
battery.
The
device
is
packaged in a 14-pin QFN PowerPAD package
measuring 3 × 4 mm (DSJ).
