Product Description

The LMR14050SDDA is a SIMPLE SWITCHER® Step-down Regulator with an integrated high-side MOSFET. 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. 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.
