Simple 5 volt and 3.3 volt 8A power supply circuit using LTM4628
Using the LTM4628 complete dual 8A output switching mode DC DC power controller can be designed a very simple and high efficiency power supply electronic project that can be easily configured to provide a single 2-phase 16A output.
Included in the package are the switching controller, power FETs, inductor, and all supporting components. Operating from an input voltage range of 4.5V to 26.5V, the LTM4628 supports two outputs each with an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 8A continuous current for each output. Only a few input and output capacitors are needed.
LTM4628 has an onboard temperature diode for device temperature monitoring.
High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
This power supply electronic project will provide a 5 and 3.3 volt output voltage at a maximum output current of 8 amperes .
The input voltage required to power this DC DC converter electronic project must be around 24 volt .
The LTM4628 modules do not provide galvanic isolation from VIN to VOUT. There is no internal fuse.
