The LTM8021 is a 36VIN 500mA, step-down DC/DC μModule® (power module). 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 finish the design.

The low profile 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 profile (2.82mm) overmolded Land Grid Array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM8021 is RoHS compliant.

Applications

  • Automotive Battery Regulation
  • Power for Portable Products
  • Distributed Supply Regulation
  • Industrial Supplies
  • Wall Transformer Regulation

Product Detail

Demonstration circuit 1238B features the LTM8021, a 36V 500mA step-down μModule® regulator. The output has been preset to 5V by a single resistor within the LTM8021’s output voltage range of 0.8V to 5V. An adjustable soft-start period may be implemented with the addition of a capacitor at C3. The input voltage range is from 7.5V to 36V for the default operating conditions. The LTM8021 may need more input voltage to start up than to run in steady state.
