TPS610995YFFT Integrated Circuits (ICs)

1. Description

The TPS610995YFFT device is synchronously boosted Converter with 1µA ultra-low quiescent current. This The device is designed to be used by Alkaline battery, Ni-MH rechargeable battery, Lithium manganese Battery or lithium ion rechargeable battery, Efficiency under light load conditions To achieve a longer battery life. TPS610995YFFT boost converter uses hysteresis Control the topology for maximum efficiency in Minimum quiescent current. Only consumes 1-µA The quiescent current under light load conditions can In a fixed case, the efficiency is as high as 75% under a load of 10µAOutput voltage version. It can also support up to 300 MA output current converted from 3.3 V to 5 V, and A voltage of up to 93% can be achieved under a load of 200mA. TPS610995YFFT also provides Down Mode and Down Mode. Direct operation for different applications. in In step-down mode, the output voltage can still be adjusted Reach the target value even if the input voltage is higher than the target voltage The output voltage. In the pass-through mode, the output

The voltage follows the input voltage. TPS610995YFFT exit Down mode and enter pass-through mode When VIN> VOUT + 0.5 V.

TPS610995YFFT supports true shutdown function When disabled, it will disconnect the load from Input power to reduce current consumption. TPS610995YFFT provides two adjustable output voltages Version and fixed output voltage version. it is Provide 6-ball 1.23mm x 0.88mm WCSP package Package and 6-pin 2mm x 2mm WSON package.
