Sync Boost Regler, Low IQ ET82097V50
NCNR (non cancelable / non returnable)
Synchronous Boost Converter, ET82097V50, ETEK Microelectronics
The ET82097V50 device 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 ET82097V50 offers different fixed output voltage versions. Hysteric control topology has been employed to obtain maximal efficiency at minimal quiescent current. ET82097V50 can achieve up to 80% efficiency at 100µA load.
It can also support up to 300mA output current from 3.3V to 5V conversion, and achieve up to 93% at 200mA load. The ET82097V50 supplies both Down Mode and Pass-Through operations for different applications. In Down Mode, the output voltage can still be regulated at target value even when input voltage is higher than output voltage. In Pass-Through Mode, the output voltage follows input voltage.
