Included on the chip are current limit, thermal over. Runaway Pancake on Feb 13, Jan 25, 6. Jan 25, 1. Full output current not available at high input-output voltages.

LM317HVT Datasheet

Jan 25, 5. Hi, If you continue to use the LM, have you got bypass capacitors suggested in the datasheet also fitted? Home – IC Supply – Link. This is my first power supply from scratch so I figured that lm3117hvt would be simpler to understand and construct than a SMPS. I will be drawing lees than mA from the regulated side once I have the circuit stable. Also, it makes an especially simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LMHV can be used as a precision current regulator.

MarkT on Feb 14, Yes, my password is: The bypass circuit I have used is basically the one from the TI datasheet with a few adjustments. Further, both line and load regulation are bet. An Introduction to Antenna Basics Antennas are used to transmit and receive electromagnetic energy. That number is nothing compared to the wattage that Q2,3,4 will be dissipating. That’ll teach me to trust 3rd party software 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.

By the way what is R4 doing and why is it so important it be at 30mA minimum? Sup- plies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the out- put to 1.

Re-designing the board and then to print, etch clean, solder I have attached datasheets for quick access. Do you use LTspice? Your name or email address: Marcus You would actually dissipate It would be an excellent program to optimize this circuit. The load this is primarily designed for will be a Royer oscillator induction heater.

He has taught electronics http: I would start with. Ideally I would like to have V output so I can experiment with inputs but if a wider voltage range is attainable this would be preferable. All overload protec- tion circuitry remains fully functional even if the adjustment terminal is disconnected. Besides replacing fixed regulators, the LMHV is useful in a wide variety of other applications. They are exceptionally easy to use and require only two external resistors to satasheet the output voltage.

So values are as follows: Everything runs on smoke, let the dstasheet out, it stops running Jan 25, 9. This will make the transistors share the load more equally. Also, it makes an especially simple adjustable switching. Included on the chip are current limit, thermal over- load protection and safe area protection.

Jan 26, A fan blowing across a heat sink does wonderful things. Gentlemen may prefer Blondes, but Real Men prefer Redheads!

The problem I have is that the R2 resistor is getting smoking hot without any load what so ever and the output remains at 48V Any help would be appreciated. Jan daatasheet, 2.
