Description
General part information
LMR14050-Q1 Series
The LMR14050-Q1 is a 40V, 5A step down regulator with an integrated high-side MOSFET. With a wide input range from 4V to 40V, the device is designed for various applications from industrial to automotive for power conditioning from unregulated sources. An extended family is available in 2A and 3.5A options in pin-to-pin compatible packages, including LMR14020-Q1 and LMR14030-Q1. The regulator quiescent current is 40µA in sleep mode, which is designed for battery powered systems. An ultra-low 1µA current in shutdown mode can further prolong battery life. A wide adjustable switching frequency range allows either efficiency or external component size to be optimized. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This feature 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 LMR14050-Q1 is available in an 8-pin HSOIC or 10-pin WSON package with exposed pad for low thermal resistance.
