ISL91133IIL-EVZ

ISL91133IIL-EVZ is an evaluation board allows for quick evaluation of the ISL91133 integrated boost switching regulator for battery-powered applications. The ISL91133 is an integrated boost with bypass switching regulator for battery powered applications. The device provides a power supply solution for products using 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 evaluation board allows quick evaluation of the high performance features of this regulator. Application includes smartphones and tablet PCs, wireless communication devices, 2G/3G/4G RF power amplifiers, USB OTG power source.
