The LT ? 3695 series are adjustable frequency (250kHz to
2.2MHz) monolithic buck switching regulators that accept
input voltages up to 36V and can safely sustain transient
voltages up to 60V. The devices include a high ef?ciency
switch, a boost diode, and the necessary oscillator, control
and logic circuitry. Current mode topology is used for fast
transient response and good loop stability. A SYNC pin
allows the user to synchronize the part to an external clock,
and to choose between low ripple Burst Mode operation
and standard PWM operation.
The LT3695 regulators tolerate adjacent pin shorts or
an open pin without raising the output voltage above its
programmed value.
Low ripple Burst Mode operation maintains high ef?-
ciency at low output currents while keeping output ripple
below 15mV in a typical application. Shutdown reduces
input supply current to less than 1μA while a resistor and

capacitor on the RUN/SS pin provide a controlled output
voltage ramp (soft-start). Protection circuitry senses the

current in the power switch and external Schottky catch
diode to protect the LT3695 regulators against short-circuit
conditions. Frequency foldback and thermal shutdown
provide additional protection.
