DC1194A: 3.3V @ 200mA, 4.5 ~ 36V in, Inductor On-Chip

Demonstration circuit DC1194A features the LTM®8020, a 200mA DC/DC step-down μModule® regulator. The board is preset to deliver a 3.3V output at up to 200mA load current from an input voltage of up to 36V. The output voltage may be modified by simply changing one resistor.

The LTM®8020 is a complete 200mA, 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 4V to 36V, the LTM8020 supports an output voltage range of 1.25V to 5V, set by a single resistor. Only bulk capacitors are needed to finish the design. The LTM8020 meets the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components.

The low profile (2.32mm) tiny package enables utilization of unused space on the bottom of PC boards for high density point of load regulation.
