General Description
The ET82097BV28 is a synchronous boost converter with ultra-low quiescent current. The device is designed for products powered by an alkaline battery, lithium battery or rechargeable Li-Ion battery, for which high efficiency under light load condition is critical to achieve long battery life operation.
The ET82097BV28 offers 2.80V fixed output voltage. Hysteric control topology has been employed to obtain maximal efficiency at minimal quiescent current. ET82097BV28 can achieve up to 80% efficiency at 100µA load. It can also support up to 300mA output current, and achieve up to 93% at 200mA load.
The ET82097BV28 supplies Pass-Through operations for different applications. In Pass-Through Mode, the output voltage follows input voltage.
The ET82097BV28 available in SOT23-5 Package.
