    Cycles* Applications n n n The LTВ®1767 is a 1.25MHz monolithic buck switching
    regulator. A high efficiency 1.5A, 0.22О© switch is included
    on the die together with all the control circuitry required
    to complete a high frequency, current mode switching
    regulator. Current mode control provides fast transient
    response and excellent loop stability. ...
