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 significantly reduces the standby consumption.
The ISL91133 offers a Bypass mode operation where the output is directly connected to the input through a 38mΩ MOSFET to allow a significantly lower dropout voltage. The Bypass mode can be entered by an external command, or by auto bypass.
