The TPS6300x devices provide a power supply
from 1.2V to 5.5V
solution for products powered by either a two-cell or

controller using synchronous rectification to obtain
maximum efficiency. At low load currents, the
• Available in Small 3 mm × 3 mm, QFN-10
converter enters Power Save mode to maintain high
Package
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).
