LTM8022EV#PBF

LTM8022 is a complete 1A, DC/DC step-down power supply. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.6V to 36V, this device supports an output voltage range of 0.8V to 10V, and a switching frequency range of 200KHz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design. It enables utilization of unused space on the bottom of PC boards for high density point of load regulation. It is used in applications such as automotive battery regulation, power for portable products, distributed supply regulation, industrial supplies, wall transformer regulation.
