LTM4612 High Density 5A High Voltage Low Noise Step-Down Regulator

Typical 22V to 36VIN, 12V at 5A Design

The LTM®4612 is a EN55022 Class B certified high voltage input and output, 5A switching mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 5V to 36V, the LTM4612 supports an output voltage range of 3.3V to 15V, set by a single resistor. Only bulk input and output capacitors are needed to finish the design.
