DESCRIPTION

The LT®3663 is a 1.5MHz current mode step-down switching regulator 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 Internal compensation and boost diode minimize the number of external exponents.
