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.
