Part Number: LM5025 Hi all, in our application we've used a LM5025 controller in a forward topology with active clamp.
In our design (see attachment), we have connected both CS1 and CS2 to the same current measurement, using two different time constants…
Part Number: LM5025 Hello ,
We are using LM5025 and requirements to power supply to make the operational at Vin 15Vdc,
Since LM5025 min operating input range is 13Vdc, Hence can't set Input UVLO below 13V.
We have tested Input UVLO at 13.8V and recover…
Part Number: LM5025 Other Parts Discussed in Thread: LM5020 , UC1843 , I am working with a power supply project. The project has two power module which switching frequency must be between 400kHz ~ 600kHz.
module 1 : Vin 20V~34V ; Vout : +5V/16A -5V0.5A
module…
Part Number: LM5025 Hi team,
This is Brandon. met a problem on LM5025 design.
The internal pull-up voltage of the COMP pin of the chip is 5V, and the pull-up resistance is 5kohm.
According to the connection method in the current schematic diagram, the…
Part Number: LM5025 Hi team,
I got a question from customer.
Ramp to get the maximum duty cycle limit after comparing with 2.5V fixed voltage. Why is formula (4) used to calculate RC formula in 8.2.2.3 on page 19 of lm5025 data manual?
If you only look…
Part Number: LM5025 Other Parts Discussed in Thread: UCC2897A Hi Team,
Can LM5025 be used for boost topology? Is there any reference schematic for this? Thanks!
Regards,
Part Number: LM5025 Hello. I create a power supply with an active clamp with your Lm5025 microcontroller. But I cannot find the order of calculation of the elements. Can you send them to me, or are they secret?
Part Number: LM5025 in Lm5025 there is an internal regulator that provides the initial Vcc .but when converter reaches steady state it is suggested to provide vcc through a coupled inductor which will turn off the internal regulator
.If I operate it without…
Part Number: LM5025 Hi Team,
A customer requests the variation data of CS1 threshold(cycle by cycle threshold) at Tj=25C. Though this parameter has specified with MIN(0.22V) & MAX(0.28V) value over -40 to 125C range, For Tj=25C, it is only typ value(0…
Part Number: UCC2897A Other Parts Discussed in Thread: LM5025 , LM5026 Tool/software: Hi Team,
We are looking for Active Clamp Forward converter controllers with following design specifications:
Input Voltage – 9V to 60V (28V Steady state)
Output…
