The LT
1765 is a 1.25MHz monolithic buck switching
regulator. A high efficiency 3A, 0.09
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.
New design techniques achieve high efficiency at high
switching frequencies over a wide operating voltage range.
A low dropout internal regulator maintains consistent
performance over a wide range of inputs from 24V
systems to Li-Ion batteries. An operating supply current
of 1mA improves efficiency, especially at lower output
currents. Shutdown reduces quiescent current to 15
μ
A.
Maximum switch current remains constant at all duty
cycles. Synchronization allows an external logic level
signal to increase the internal oscillator into the range of
1.6MHz to 2MHz.
Full cycle-by-cycle current control and thermal shutdown
are provided. High frequency operation allows the reduc-
tion of input and output filtering components and permits
the use of chip inductors.
