Step-Down converter with integrated high-side MOSFET for automotive battery regulation

Texas Instruments LMR16030 60V 3A SIMPLE SWITCHER step-down converter, available now from Mouser, is a step-down regulator with an integrated high-side MOSFET. With a wide input range from 4.3V to 60V, it’s suitable for various applications from industrial to automotive for power conditioning from unregulated sources. The regulator’s quiescent current is 40µA in sleep mode, which is suitable 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 optimised. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimises the external components of the device. Typical application uses are in automotive battery regulation, industrial power supplies, telecom and datacom systems, and general purpose wide vin regulation.
