Texas Instruments TPS610992YFFR
The TPS61099x device is a synchronous boost converter with 1-µA ultra-lowquiescent current. The device is designed for products powered by an alkaline battery, NiMHrechargeable battery, Li-Mn battery or rechargeable Li-Ion battery, for which high efficiency underlight load condition is critical to achieve long battery life operation.
The TPS61099x boost converter uses a hysteretic control topology to obtain maximalefficiency at minimal quiescent current. It only consumes 1-µA quiescent current under light loadcondition and can achieve up to 75% efficiency at 10-µA load with fixed output voltage version. Itcan also support up to 300-mA output current from 3.3 V to 5 V conversion, and achieve up to 93% at200-mA load.
The TPS61099x also offers both Down Mode and Pass-Through operations for differentapplications. In Down Mode, the output voltage can still be regulated at target value even wheninput voltage is higher than output voltage. In Pass-Through Mode, the output voltage follows inputvoltage. The TPS61099x exits Down Mode and enters into Pass-Through Mode whenVIN > VOUT + 0.5 V.
The TPS61099x supports true shutdown function when it is disabled, which disconnects theload from the input supply to reduce the current consumption.
The TPS61099x offers both adjustable output voltage version and fixed output voltageversions. It is available in 6-ball 1.23-mm x 0.88-mm WCSP Package and 6-pin 2-mm x 2-mm WSONpackage .
