Nettet25. okt. 2024 · However, you could parallel the outputs of several totally independent current sources, each with its own power device, Rs and opamp. Most MOSFETs will not like operating in linear mode like this, they are designed and specified for switching operation. Internally, MOSFETs are hundreds, if not thousands, of separate small FETs. Nettet9. des. 2024 · Re: Transistor VS MOSFET for linear power supply. I think you will find that MOSFETs make excellent switches but poor linear elements. If it was simple to pull out the transistor and drop in a MOSFET, there wouldn't be any transistors used for pass elements. But, no, we use a 55 year old 2N3055 or even several in parallel.

NettetDescription: OptiMOS™ Linear FET is a revolutionary approach to avoid the trade-off between on-state resistance (R DS (on)) and linear mode capability – operation in the saturation region of an enhanced mode MOSFET. It offers the state-of-the-art R DS (on) of a trench MOSFET together. Package Type: TO-263, Other. Nettet30. jun. 2016 · 1,618. Hi guys, I have a question. I dont normally see IGBT's or mosfets being used in linear power supplies. Many of the components on these are only rated for their output load when TJ = 25C and the transistor quickly burns under short circuit conditions. For a 0-30V 5A (or 0-60V 2.5A) power supply to be fool proof, even if … NettetThe part has. integrated input current, input voltage, output current. and output voltage feedback loops. With a wide 2.8V to. 80V input and 1.3V to 80V output range, the LT8705 is. compatible with most solar, automotive, telecom and. battery-powered systems.
