Dear support,
On my adjustable output voltage application I currently use the LM2678SX-ADJ reference but I would need some alternative references.
Can the LM2677…
Part Number: LM2678 Hi Team,
Good day. I am posting this inquiry on behalf of the customer.
"I plan to use LM2678S-12 as 26-27V regulator driving feedback (FB pin) through resistor instead of direct voltage output, see below.
Used formula from datasheet…
Part Number: LM2678 Hi,
The peak current pulse of Iout is over rated current 5A in my schematic.
The peak current pulse is 7A at 264us.
The continuous current is 1.7Arms.
In this case, The current limit don’t work.
I want to know that what value…
Part Number: LM2678 Other Parts Discussed in Thread: LM3880 , Hi,
I use the LM3880 of power sequencer and LM2678 of DCDC.
Please see attached my schematic.
I have a problem.
The ON/OFF voltage of LM2678 becomes approximately 4V.
My expectation is 3.3V. …
Part Number: LM2678 Other Parts Discussed in Thread: LM76005 , Hi,
I have two questions about the LM2678SD-ADJ.
Q1:Does the LM2678SD-ADJ have a risk of internal circuit short between Vin(Input) and Vout(Switch output) ?
Q2:Could you give me the report of…
Part Number: LM2678 Hi there!
I'm designing a buck converter that converts the voltage around 20v-40v to 5.5v at 3.5A. I followed the WEBench guides, but I don't know exactly what's wrong with my design, below are pictures of the circuit. I…
Part Number: LM2678 I have a problem of voltage drop on LM2678SD-5.0.
I understand 5V fixed voltage about LM2678SD-5.0.
But I must resolve voltage drop using LM2678SD-5.0.
I expect to become to voltage increasing that I add series resistor on FB pin. …
Part Number: LM2678 I want to design a power supply that can switch between 5V and 12V outputs, 4.5 amps max, 34-38V input. Looking at LM2678. Using the design information Cin, Cout, and L1 are quite different between a 5V design and a 12V design. Which…
