The Texas offers a TPS family of devices provide a power supply solution for products powered by alkaline battery output currents can go as high as 200 mA while using a single-cell. At low load currents the converter enters the power save mode can be disabled, forcing the converter to operate at a fixed switching frequency. 96% Efficient synchronous boost converter
Device quiescent current of 25 μA
Input voltage range of 0.9 V to 6.5 V
