High-Efficiency 2.3A Boost Regulator with Input-to-Output Bypass Evaluation Boards

The ISL91133IIx-EVZ evaluation boards allow for quick evaluation of the ISL91133 integrated boost switching regulator for battery-powered applications.

The ISL91133 is an integrated boost-with-bypass switching regulator for battery-powered applications. The device provides a power supply solution for products using a one-cell Li-ion or Li-polymer battery. It is capable of delivering up to 2.3A output current from V_IN = 2.5V and V_OUT = 3.3V. The no-load quiescent current is only 108μA in Boost mode and 45μA in Forced Bypass mode, which significantly reduces the standby consumption.
