Part Number: LM317HV I need a low ripple, clean +- 48 or +- 50 v supply. I am going to use linear regulator after filtering the output of DC/DC converter. I can't find a complimentary product of LM317HV or a design for using it in Dual output power.…
Part Number: LM5022 Other Parts Discussed in Thread: LM317HV , LM317 , LMP8646 , LM5177 , LM5118 Hello Team,
We have a battery of upper charge limit 54.6. The input is 48V from an adapter. We want to charge it with a max 3A current limit.
We came…
Hi Stephen,
I built a circuit and did some experiments. The schematic is as below, and the load is a 1k resistance.
I used two method to start the DC power source. The first is to use the button of DC power source, the ramp rate is slow. The secon…
Hey Shruthi,
1) Both the LM3578AM/NOPB ( https://www.ti.com/store/ti/en/p/product/?p=LM3578AM/NOPB ) and the LM317HVT/ NOPB ( https://www.ti.com/product/LM317HV ) are ACTIVE parts see links for product pages.
2) For the RoHS please use this lookup tool: …
Hi Kami,
That is a lot of power you are trying to dissipate with an LDO. We don't have too many devices in our portfolio that can truly handle this, the ones that can are non-Q100: LM117HV and LM317HV. Unfortunately we do not have anything automotive…
Other Parts Discussed in Thread: LM317HV Hello
Do you have below solution:Vin 12V convert to -5V ~ +50V/100mA ; or output could be -5V ~ 0V combined with 0V ~ +50V , thanks
Part Number: TL783 Other Parts Discussed in Thread: LM317 , , LM317HV Can this chip use the popular LM317 soft start method?with a HV pnp BJT plus appropriate working voltage capacitor.
Targeted regulated voltage is around 250V or lesser.
Hi Thomas,
Thanks for this information and suggestions. I will pursue this further.
I do have one follow up question. By setting the LM317HV to 50mA, the OPA454 output can source up to 50mA since it will be the "lower" current source. However…
