Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: LM2594HV I have a design where I am using the LM2594HV-12V. The load current is approximately 200mA with a short (500uS) startup peak of 295mA. input voltage is 48Vdc and output voltage is 12V. Below a measurement taken when using a lab supply…
When thermal shutdown (or even temporary output short) the output voltage drops to something like 0.5V but the inductor and the associated capacitor get very hot and prevent the regulator from recovery even after a power cycle, or at least until the inductor…
Other Parts Discussed in Thread: LM2594HV hi !
i am trying to use LM2594HV in my design but i am having trouble interpretting the data sheet , even digikey employees were lost at
finding the right component for this design.
i need your help urgently to…
I am designing a 10V power supply using your LM2594HV-ADJ IC.
As mentioned in the datasheet, pin 5 has a !ON/OFF function and pins 1, 2 and 3 are not connected.
But in the 'typical PCB layout' for an adjustable output, in the same datasheet, pins 1 and…
Other Parts Discussed in Thread: LM2594 Webbench seems to be making wrong inductor calculations, at least for LM2594.
48V input, 12V output at 0.200 A.. select LM2594HV-12 solution. It recommends 22uH.
However this value is way too low. The data sheet…
Other Parts Discussed in Thread: LM22671 Hello,
I have question about LM2594HVMX-5.0. What is the thermal shutdown temperature ? Best regards, Makoto Shiraishi
Hello, I'm designing a power supply with the LM2594HV-ADJ.
Vin = 56V, Vout = 24V, Iout = 0.5A.
The datasheet gives a 330uH value for the coil.
The webbench tool gives a 680uH value for the coil.
What's the best value?
Regards,
Roel Lenssen
Part Number: LM22676 Other Parts Discussed in Thread: LM2594HV , , LM46000 I have two questions.
I am using the LM22676MRE-5.0 and I need a 50V or higher input voltage device. I only need 0.7A max output, operating temp range will be 15-40C. I found the…
Other Parts Discussed in Thread: LM2594HV , LM34910C , LM46000 I have been asked to provide a power supply with the following specifications:
Non-Isolated
AC/DC input
The AC input terminals already have a bridge rectifier input on the ac side is 12 to …

Mark,
Your question is posted in the Linear Regulators Forum, not the proper place for Simple Switcher (i.e. LM2594M-ADJ) questions.
This thread will be moved to the Simple Switcher…
