Cycles* Applications n n n The LT®1767 is a 1.25MHz monolithic buck switching
regulator. A high efficiency 1.5A, 0.22Ω 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. …
