DATASHEET ISL91134 High Efficiency 1.8A Boost Regulator With Input-to-Output Bypass FN8678 Rev.2.00 Dec 20, 2018 The ISL91134 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 1.8A output current from VIN = 3V and VOUT = 5V.

The no-load quiescent current is only 108µA in Boost Mode and 45µA in Forced Bypass Mode, which sig
