LMR14020SQDDAQ1

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4В-40В (Vin), 800мВ-28В/2А, 1.912МГц, HSOP-8.

The LMR14020SQDDAQ1 is a 40V, 2A step down converter with 40µA IQ in 8 pin HSOP package. With a wide input range from 4V to 40V it is 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. It 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. It is used in telecom and datacom systems, general purpose wide Vin regulation and industrial power supplies.
