LTM8021EV#PBF

LTM8021 is a 36VIN, step-down DC/DC µModule®. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3V to 36V, it supports an output voltage range of 0.8V to 5V, set by a single resistor. Only an output and bulk input capacitor 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. A built-in soft-start timer is adjustable with just a resistor and capacitor. It is used in applications such as automotive battery regulation, power for portable products, distributed supply regulation, industrial supplies, wall transformer regulation etc.
