Overview
Product Details
Demonstration circuit 1730A features the LT3973, a monolithic step-down switching regulator which consumes only 2.5μA quiescent current. The demo circuit is designed for a 5V, 750mA output from a 5.6V to 42V input. The wide input range of the LT3973 allows a variety of input sources including automotive batteries and 24V industrial supplies. In order to reduce the number of components and solution size, the catch diode and boost diode are integrated. The switching frequency is adjustable up to 2.2MHz. At light loads, the regulator operates in Burst Mode® to maintain high efficiency and low output ripple.
