    n 10-Lead MSOP and DFN Packages The LTВ®3999 is a monolithic, high voltage, high frequency
    DC/DC transformer driver providing isolated power in a
    small solution footprint. n The LT3999 has two 1A current limited power switches
    that switch out of phase. The duty cycle is programmable
    to adjust the output voltage. The switching frequency is
    programmed up to 1MHz and can be synchronized to an
    external clock for more accurate placement of switcher
    harmonics. The input operating range is programmed ...
