Marcus You would actually dissipate They are exceptionally easy to use and require only two external resistors to set the output voltage.

Besides replacing fixed regulators, the LMHV is useful in. Now the problems I have come across are as follows: Having searched through the forums for LM high current supplies I have found some very helpful threads, mainly this one LM thread link So after viewing other circuits and consulting the LMHVT datasheet I have come up with the following design which ideally would give me a maximum voltage in-out differential of 60V.

Trouble with a LMHVT

LMHV can be used as a precision current regulator. He has taught electronics http: I have attached datasheets for quick access. Re-designing the board and then to print, etch clean, solder Sup- plies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the out- put to 1.

LMHVT Datasheet

I would start with. By the way what is R4 doing and why is it l317hvt important it be at 30mA minimum? Jan 25, 4. High voltage adjustable bipolar power supply Posted by coinmaster in forum: Regards, Terry King terry yourduino.

Further, both line and load regulation are bet- ter than standard fixed regulators. An optional output capacitor can be added to improve transient response.

Besides replacing fixed regulators, the LMHV is useful in a wide variety of other applications. Do you use LTspice? MarkT on Feb 15, The problem I have is that the R2 resistor is getting smoking hot without any load what so ever and dztasheet output remains at 48V Any help would be appreciated.

A fan blowing across a heat sink does wonderful things. Feb 22, Jan 25, 6. The load this is primarily designed for will datashedt a Royer oscillator induction heater.

[FOLLOW UP] Adjustable LM317HVT High current supply design

Also, it makes an especially simple adjustable switching regulator, a lm317hvg output regulator, or by connecting a fixed resistor between the adjustment and output, the LMHV can be used as a precision current regulator. I will be drawing lees than mA from the regulated side once I have the circuit stable.

Jan 25, 8. LMHV series offers full overload protection available only. So values are as follows: Reliability reduces as running temperatures go up too. The adjustment terminal can be bypassed to achieve very high ripple rejections ratios which are difficult to achieve with standard 3-terminal regulators.

MarkT Brattain Member Posts: TomGeorge Design and Repair of industrial control systems. Further, both line and load regulation are bet. Gentlemen may prefer Blondes, but Real Men prefer Redheads! Note about the load: No, create an account now.
