LMR16030PDDA Description

The LMR16030PDDA 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.
