TPS63700DRCT

The TPS63700DRCT is an Inverting DC/DC Converter generating a negative output voltage down to -15V with output currents up to 360mA, 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 to 5.5V allows it to be directly powered from a Li-ion battery, from 3-cell NiMH/NiCd, from a 3.3 or 5V 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 1.4MHz allows the use of small external components enabling a small solution size.
