Description

The SM6001 is an easy to use 36 V and 1 A synchronous step-down regulator. With a wide input range from 4 V to

36 V, it is suitable for various applications from industrial to

automotive for power conditioning from unregulated sources. Peak current mode control is employed to achieve simple control loop compensation and cycle-by-cycle current limiting, and a quiescent current of 75 μA makes it suitable for battery powered systems. The internal loop compensation means that the user is free from the tedious task of loop compensation design, and this also minimizes the need for external components. In addition, the precision enable input allows the simplification of regulator control and system power sequencing. Protection features include cycle-by-cycle current limit, hiccup mode short circuit protection and thermal shutdown due to excessive power dissipation.
