Description
The TPS610997YFFT device is a synchronous boost converter with 1-µA ultra-low quiescent current. The device is designed for products powered by an alkaline battery, NiMH rechargeable battery, Li-Mn battery, or rechargeable Li-Ion battery where high efficiency under light-load condition is critical to achieve long battery life operation.
The TPS610997YFFT boost converter uses a hysteretic control topology to obtain maximal efficiency at minimal quiescent current. It only consumes 1-µA quiescent current under light-load condition and can achieve up to 75% efficiency at 10-µA load with fixed output voltage version. It can also support up to 300- mA output current from 3.3-V to 5-V conversion, and achieve up to 93% at 200-mA load.
