The LMR16030 is a 60-V, 3-A SIMPLE SWITCHER step-down regulator with an integrated high-side MOSFET. With a wide input range from 4.3 V to 60 V, it is suitable for various applications from industrial to automotive for power conditioning from unregulated sources. The quiescent current of the regulator is 40 µA in sleep mode, which is suitable for battery-powered systems. An ultra-low 1-µA 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 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 LMR16030 is available in an 8-pin HSOIC package with exposed pad for low thermal resistance.

The new product, LM76003, requires very few external components and has a pinout designed for simple, optimum PCB layout for EMI and thermal performance. See the device comparison table to compare specs.
