    ■ ■ DESCRIPTIO The LT ®1680 is a high power, current mode switching
    power supply controller optimized for boost topologies.
    The IC drives an N-channel MOSFET switch for DC/DC
    converter applications up to 60V input. A high current gate
    drive output handles up to 10,000pF gate capacitance,
    enabling the construction of high power DC/DC converters. Current sense common mode range up to 60V allows
    current sensing to be referenced to the input supply,
    eliminating the need for sense blanking circuits. High Voltage: Operation Up to 60V
    High Current: N-Channel Drive Handles Up to
    10,000pF Gate Capacitance
    Programmable Average Current Limiting
    5V Reference Output with 10mA External
    Loading Capability
    Fixed Frequency Current Mode Operation
    Oscillator Synchronizable Up to 200kHz ...
