Texas Instruments TPS61099x Synchronous Boost Converters

Texas Instruments TPS61099x Synchronous Boost Converters operate with a 1µA ultra-low quiescent current. The device is designed for products powered by alkaline NiMH rechargeable, Li-Mn, or rechargeable Li-Ion batteries. This device is intended for which high efficiency under light load conditions is critical to achieving a long battery life operation. The TPS61099x boost converter uses a hysteretic control topology to obtain maximal efficiency at minimal quiescent current. The device only consumes 1µA quiescent current under light load conditions and can achieve up to 75% efficiency at 10µA load with fixed output voltage version. The TPS61099x can also support up to 300mA output current from 3.3V to 5V conversion and achieve up to 93% at 200mA load.
