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 significantly reduces the standby consumption.
The ISL91134 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.
