The TPS63700 is an inverting DC/DC converter generating a negative output voltage down to
–15 V with output currents up to 360 mA, depending on input-voltage to output-voltage ratio. With a
peak efficiency of 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 inverter operates with a fixed-frequency pulse width modulation (PWM) control
topology. The device has an internal current limit, overvoltage protection, and a thermal shutdown
for highest reliability under fault conditions.
A switching frequency of typically 1.4 MHz allows the use of small external components
enabling a small solution size.
The TPS63700 comes in a small 3-mm × 3-mm SON-10 package.
