The TPS61099x is a synchronous boost converter with 1-µA ultra-low quiescent current. It is designed for products powered by an alkaline battery, NiMH rechargeable battery, Li-Mn battery or rechargeable Li-Ion battery, for which high efficiency under light load condition is critical to achieve long battery life operation.
●The TPS61099x boost converter uses a hysteretic control topology to obtain maximal efficiency at minimal quiescent current. It only consumes 1-µA quiescent current under light load condition and can achieve up to 75% efficiency at 10-µA load with fixed output voltage version. It can also support up to 300-mA output current from 3.3 V to 5 V conversion, and achieve up to 93% at 200-mA load.
●The TPS61099x also offers both Down Mode and Pass-Through operations for different applications. In Down Mode, the output voltage can still be regulated at target value even when input voltage is higher than output voltage. In Pass-Through Mode, the output voltage follows input voltage. The TPS61099x exits Down Mode and enters into Pass-Through Mode when VIN > VOUT \\+ 0.3 V.
●The TPS61099x supports true shutdown function when it is disabled, which disconnects the load from the input supply to reduce the current consumption.
●The TPS61099x offers both adjustable output voltage version and fixed output voltage versions. It is available in 6-ball 1.23-mm x 0.88-mm WCSP Package.
