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.

The inverter TPS63700 operates with a fixed-frequency PWM control topology. The TPS63700 has an internal current limit, overvoltage protection, and a thermal shutdown
for highest reliability under fault conditions.
