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 1800 mA. 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 10-pin QFN PowerPAD™ package

measuring 3 mm × 3 mm (DRC).
