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 dro...
