Monolithic 3A, 1.25MHz
Step-Down Switching Regulator
FEATURES DESCRIPTION n The LT®1765 is a 1.25MHz monolithic buck switching
regulator. A high efficiency 3A, 0.09Ω switch is included
on the die together with all the control circuitry required
to construct a high frequency, current mode switching
regulator. Current mode control provides fast transient
response and excellent loop stability. 3A Switch in a Thermally Enhanced 16-Lead
