DATASHEET ISL91133 High Efficiency 2.3A Boost Regulator with Input-to-Output Bypass FN8680 Rev 1.00 Jul 12, 2018 The ISL91133 is an integrated boost 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. The device is capable of delivering up to 2.3A output current from VIN = 2.5V and VOUT = 3.3V. The no load quiescent current is only 108μA in Boost mode and 45μA in Forced Bypass mode, which.

ISL91133 Features

* Input voltage range: 2.35V to 5.4V
