3684f
36V, 2A, 2.8MHz Step-Down
Switching Regulator
The LT
3684isanadjustablefrequency(300kHzto2.8MHz)
monolithic buck switching regulator that accepts input
voltages up to 34V (36V maximum). A high efciency
0.18
Ω switch is included on the die along with a boost
Schottky diode and the necessary oscillator, control and
logic circuitry. Current mode topology is used for fast
transient response and good loop stability. The LT3684’s
high operating frequency allows the use of small, low cost
inductors and ceramic capacitors resulting in low output
ripple while keeping total solution size to a minimum.
The low current shutdown mode reduces input supply
current to less than 1A while a resistor and capacitor on
the RUN/SS pin provide a controlled output voltage ramp
(soft-start). A power good ag signals when VOUT reaches
90% of the programmed output voltage. The LT3684 is
available in 10-Pin MSOP and 3mm
× 3mm DFN packages
with Exposed Pads for low thermal resistance.
