    Constant-Current/
    Constant-Voltage 1.4MHz
    Step-Up DC/DC Converter U FEATURES DESCRIPTIO ■ The LT®1618 step-up DC/DC converter combines a traditional voltage feedback loop and a unique current feedback
    loop to operate as a constant-current, constant-voltage
    source. This fixed frequency, current mode switcher operates from a wide input voltage range of 1.6V to 18V, and
    the high switching frequency of 1.4MHz permits the use of
    tiny, low profile inductors and capacitors. The current
    sense voltage is set at 50mV and can be adjusted using the
    IADJ pin. ■
