32 volt switching power supply using LTM4096
A very simple high efficiency switching mode buckboost power supply circuit can be designed using the LTM4609 switching regulator IC . This switching power supply circuit will provide an fixed output voltage of 32 volt . As you can see in the schematic circuit , this switching power supply circuit require few external electronic components .
Included in the package are the switching controller, power FETs and support components.
LTM4609 supports an operating input voltage range of 4.5V to 36V and supports an output voltage range of 0.8V to 34V, set by a resistor. This high efficiency design delivers up to 2A continuous current in boost mode .
Only the inductor, sense resistor, bulk input and output capacitors are needed to finish the design.
The high switching frequency and current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The LTM4609 can be frequency synchronized with an external clock to reduce undesirable frequency harmonics.
Fault protection features include overvoltage and foldback current protection.
For this LTM4609 switching power supply circuit project you will require an input voltage range between 8 and 36 volt .
