    Datasheet Summary with AI

    # ISL91133 Boost Regulator

    ## Overview
    The ISL91133 is a high-efficiency boost switching regulator designed for battery-powered applications, particularly those using a single-cell Li-ion or Li-polymer battery. It provides a power supply solution with a focus on low standby consumption and compact size.

    ## Features
    · Input Voltage: 2.35V to 5.4V
    · Output Current: Up to 2.3A (at V<sub>IN</sub> = 2.5V, V<sub>OUT</sub> = 3.3V)
    · Efficiency: Up to 96%
    · Quiescent Current: 108µA (Boost Mode), 45µA (Forced Bypass Mode)
    · Switching Frequency: 2.5MHz
    · Bypass Modes: Forced Bypass & Auto Bypass (38mΩ switch)
    · Protection: Overcurrent, over-temperature, undervoltage, load disconnect
    · Package: 1.78mm x 1.78mm WLCSP

    ## Performance
    · Burst current up to 2.5A (V<sub>IN</sub> = 2.5V, V<sub>OUT</sub> = 3.3V, t<sub>ON</sub> < 600µs, T = 4.6ms)
    · Supports 6 fixed output voltages (3.15V to 5V) with voltage scaling.

    ## Applications

    · Smartphones and tablet PCs
    · Wireless communication devices
    · 2G/3G/4G RF power amplifiers
    · USB OTG power source
