3 Description
The TPS63700 is an inverting DC/DC converter generating a negative output voltage down to
- 15 V with output currents up to 360 m A, 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 Ni MH/Ni Cd, 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 ponents enabling a small solution size.
The TPS63700 es in a small 3-mm × 3-mm SON10 package.
