description  
The TPS6755 is an adjustable inverting dc/dc converter capable of operating from inputs as low as 2.7 V. The  
onlyexternalcomponentsrequiredareaninductor, anoutputfiltercapacitor, aninputfiltercapacitor, areference  
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-µA  
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-Ω 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 µA.  
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.
