Description

The LTM®8021 is a 36VIN 500mA, step-down DC/DC ModuleTM. 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, the LTM8021 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 fi nish the design.

The low profi le package (2.82mm) 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.

The LTM8021 is packaged in a thermally enhanced, compact (11.25mm * 6.25mm) and low profi le (2.82mm) overmolded Land Grid Array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM8021 is RoHS compliant.
