DATASHEET ISL91132 High Efficiency 1.8A Boost Regulator with Input-to-Output Bypass FN8637 Rev.2.00 Dec 20, 2018 The ISL91132 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 = 2.5V and VOUT = 3.3V.

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

ISL91132 Features

* Input voltage range: 2.35V to 5.4V

* Output current: up to 1.8A (VIN = 2.5V, VOUT = 3.3V)

* Burst current up to 2A (VIN = 2.5V, VOUT = 3.3V, tON < 600µs, T = 4.6ms)

* High efficiency: up to 96%

* 108µA quiescent current minimizes standby consumption in Boost
