Adjustable, -15V Output Inverting DC/DC Converter In 3x3 QFNThe 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 total efficiency 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 3-mm SON-10 package. Furthermore, 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 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. By Texas Instruments |
