EC1663|60V, 3A, Step-Down Converter

General Description

The EC1663 is a 60V, 3A step down regulator with an integrated high-side MOSFET. With a wide input
range from 9V to 60V, it’s suitable for various applications from industrial to automotive for power
conditioning from unregulated sources. An ultra-low 1μA current in shutdown mode can
further prolong battery life. Internal loop compensation
means that the user is free from the tedious task of loop compensation design. This also minimizes the
external components of the device. A precision enable input allows simplification of regulator control and
system power sequencing. The device also has built-in protection features such as cycle-by-cycle current
limit, thermal sensing and shutdown due to excessive power dissipation, and output overvoltage
protection.
The EC1663 is available in a ESOP-8 package.
