The Texas offers a TPS series of a synchronous boost converter with only 6.5-μA quiescent current and also provides a power-supply solution for products powered by alkaline battery, NiMH rechargeable battery, or one-cell Li-ion battery. This is based on a hysteretic control topology using synchronous rectification to obtain maximum efficiency at minimal quiescent current. Operating input voltage range of 0.9 V to 5.5 V
Thermal shutdown protection
Higher than 90% efficiency
