    ■ DESCRIPTIO The LT ®1619 is a fixed frequency PWM controller for
    implementing current mode DC/DC converters with minimum external parts. The LT1619 operates with input
    voltages ranging from 1.9V to 18V and is suitable for a
    variety of battery-powered and distributed DC/DC converters. The internal rail-to-rail N-channel MOSFET driver
    operates either from the input in the nonbootstrapped
    mode or from the output in bootstrapped operation. The
    driver is designed to drive a low side power transistor in
    boost, SEPIC, flyback and other topologies. Wide VIN Range: 1.9V to 18V
    300kHz Fixed Frequency Current Mode Control
    1A Rail-to-Rail N-Channel MOSFET Driver
    Low 53mV Current Limit Threshold Voltage
    Improves Efficiency
    Implements Boost, SEPIC and Flyback Converters ...
