DESCRIPTION
The LTM®4600HV is a complete 10A, DC/DC step down power supply with up to 28V input operation. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over an input voltage range of 4.5V to 28V, the LTM4600HV supports an output voltage range of 0.6V to 5V, set by a single resistor. This high effi ciency design delivers 10A continuous current (12A peak), needing no heat sinks or airflow to meet power specifi cations. Only bulk input and output capacitors are needed to fi nish the design.
