DESCRIPTION
The TPS63700 is an inverting dc-dc converter gener-
ating a negative output voltage down to –15 V with
output currents up to 360-mA, depending on in-
put-voltage to output-voltage ratio. With a total ef-
ficiency up to 84%, the device is ideal for portable
battery-powered equipment. The input voltage range
of 2.7-V to 5.5-V allows the TPS63700 to be directly
powered from a Li-ion battery, from 3-cell NiMH/NiCd,
from a 3.3-V or 5-V supply rail. The TPS63700 comes
in a small 3-mm x 3-mm SON-10 package. Further-
more, the high switching frequency of typically 1.4
MHz allows the use of small external components.
This, and the small package make a small power
supply solution possible.

DC-DC INVERTER
The inverter operates with a fixed-frequency PWM
control topology. The device has an internal current
limit, overvoltage protection, and a thermal shutdown
for highest reliability under fault conditions.
