The TPS6755 is an adjustable inverting dc/dc converter capable of operating from inputs as low as 2.7 V. The only external components required are an inductor, an output filter capacitor, an input filter capacitor, a reference filter capacitor, two resistors, and a Schottky rectifier. An enable input is provided to shut down the inverter when an output voltage is not needed. The typical supply current is 1.9 mA at no-load and is further reduced to 1-uA when the enable input is low. The device features a 160-kHz current-mode pulse-width-modulation (PWM) controller with a p-channel MOSFET power switch. The gate drive uses the converter output to reduce the die area needed to realize the 0.4-MOSFET. Soft start is accomplished with the addition of one small capacitor at SS. A 1.22-V reference is available for external loads up to 125 uA. The TPS6755 is attractive for board-level dc/dc conversion in computer peripherals and in battery-powered equipment requiring high efficiency and low supply current. Available in an 8-pin DIP or an 8-pin SOIC package, the TPS6755 operates over a free-air temperature range of - 40°C to 85°C.\n\n \n\n \n\n
