    SC8105B is a high-efficiency synchronous buck converter
    with few external components and is easy to use in compact
    applications. The device operates with input voltages from
    2.3V to 5.5V with a typical switching frequency of 2.2MHz and
    supports output voltage from 0.6V to V    IN. It integrates power
    MOSFETs and can support up to 2A load current. SC8105B
    can operate in the 100% duty cycle to offer a low input-tooutput
    voltage differential when the VIN equals VOUT.
    The device also features low quiescent current and PSM
    mode operation to maximum efficiency at light load. With
    PSM mode and low quiescent current during standby or light
    load, the device can further prolong battery life and is suitable
    for battery-powered applications.
    The device adopts a constant on-time control mode with
    internal compensation, which features excellent load transient
    performance and supports low equivalent series resistance
    output capacitors such as ceramic (MLCC) capacitors.
    SC8105B provides protections, including input under-voltage
    protection, cycle-by-cycle peak current limitation, and thermal
    shutdown protection with auto-recovery.
    SC8105B is available in FCSOT563 Package.
