TYPICAL APPLICATION
DESCRIPTION
1.2A Step-Down
Switching Regulator with
Output Current Limit
The LT3663 is a current mode step-down switching regu-
lator with programmable output current limit. The current
limit accurately controls the system power dissipation and
reduces the size of the power path components.
The wide operating input voltage range of 7.5V to 36V (60V
transient) suits the LT3663 to a variety of input sources,
including unregulated 12V wall adapters, 24V industrial
supplies, and automotive power.
The LT3663 includes a low current shutdown mode, input
overvoltage and undervoltage lockout, and thermal shut-
down. Internal compensation and boost diode minimize the
number of external exponents. 3.3V and 5V xed output
voltage versions are available.
The LT3663 is available in 8-lead DFN and MSOP packages
with exposed pads for low thermal resistance.
