Texas Instruments LMR16020 SIMPLE SWITCHER® Step-Down Converter
Texas Instruments LMR16020 60V 2A SIMPLE SWITCHER® Step-Down Converter 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 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.
