General Description

The EC1661 is a 60V, 2A 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 EC1661 is available in a ESOP-8 package
