说明

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 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.
