Part Number: LM5122 Other Parts Discussed in Thread: PMP9256 Tool/software: please share the schematic and BoM of evaluation board with transformer PA2398NL.
Part Number: LM5122-Q1 Tool/software: Hello:
The above is the schematic diagram, and the following issues were encountered during use:
1. HO output waveform is very messy and not working properly
2. Without using HO to drive MOS synchronization, using…
Part Number: LM5122 Tool/software: Hi Team,
Not long ago I've asked in another post regarding overshoot volage being too close to the NMOS voltage and Niklas suggests me a RC snubber would be a safer choice to protect the NMOS.
And I designed a…
Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122 , LM5155 , Tool/software: Hello,
I am working on a project using the LM5122QH and I noticed the datasheet does not provide a quick start calculator like the LM5155 provides on its datasheet…
Part Number: LM5122-Q1 Tool/software: I ran the TI webench power designer (18-21V in, 24V out, 8 Amps) to get a baseline design and built an eval board around these components (substituted for similar N-ch MOSFETs. I needed 60V parts for derating). It…
Hi Joseph,
Unfortunately, I did not find a reference design that does match your specs. The closest input/output parameter match was with a SEPIC design, where LM5122 is used asynchronous, meaning SW pin is connected GND and diodes are used instead of…
Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Hi,
we want to use the LM5122 as a SEPIC controller. We have a mock up that works but we want to use the current cycle-by-cycle protection as a short-circuit protection.
As…
Hi Ralph,
We have the unencrypted model files for TINA and PSpice available on the product page. Both model should come with a testbench, which can be modified to match the system requirements. The unencrypted library file can also be transferred to LTSpice…
Part Number: LM5122 Tool/software: We have an application with an LM5122 and high output capacitance (~7000µF). The input voltage is 15...30V and the output voltage should be 30V, 40V or 50V.
The implementation of MOSFET-switched parallel resistors…
Part Number: LM5122 Tool/software: Hello team,
Is it possible to set "fsync, free running with RT resistor"?
The customer needs the two same switching frequencies from RT resistor and external sync.
Best Regards,
Austin
