3VIN to 36VIN, 500mA DC/DC Switchmode Regulator from Linear Technology

The LTM8021 includes a DC/DC controller IC, power switch, inductor, compensation circuitry and input and ouwtput bypass capacitors. Its design is as simple as a linear regulator and has the advantage of less heat dissipation and smaller size. Target applications are systems with 5V, 12V, 24V and 28V input supply rails such as medical, industrial, avionics and after-market automotive.

The LTM8021 regulates an output voltage from 0.8V to 5V that is adjusted with only one resistor. Encapsulated packaging protects the circuit components against mechanical, chemical and ambient factors, thus improving the reliability of the solution. The LTM8021 is rated for operation from -40°C to 85°C and is ROHS compliant, although its gold-plated pads enable use of Pb- and Pb-free solder during board assembly.
