Ultra-Low Quiescent Current Buck-Boost Regulator with Bypass (500mA, 1.8V-5.5V Input)
Дополнительная информация
The ISL9122AIINZ-T is a highly integrated non-inverting buck-boost switching regulator designed for systems using batteries with wide voltage ranges. It features an extremely low quiescent current of 1.3µA in regulation mode and provides a peak efficiency greater than 97%. The device supports input voltages from 1.8V to 5.5V and an adjustable output voltage range of 1.8V to 5.375V via an I2C interface. It includes automatic bypass functionality and transitions seamlessly between buck and boost modes. The package is a compact 8-bump WLCSP, requiring only a single inductor and two external capacitors for a complete power solution.
