Part Number: UC1846 Tool/software: Hello:
I am stuck with tis simulation using UC1846 controller: with a feedback divider set to give 5*(1+3.73), no matter what transformer ratio I input, cannot get correct output.
In addition, cannot get even ~ 17v…
Part Number: UC1846 Tool/software:
There seems to be a problem with the model in LT spice, the simulation can not go on, and it is stuck. Please help to analyze the reason and give a solution (whether it can be solved by re-installation), thank you…
Part Number: UC1846-EP Tool/software: Hello,
What is the maximum sink current capability of the VREF pin? We are generating a VCC supply of OPAMP circuit through this pin so is it compatible of doing so?
Part Number: UC1846-SP I'd like to confirm that the referenced part (also 5962-8680603V2A) is immune to SEL and whether or not it has been tested for other types of SEE (SET, SEFI) and, if so, what is the LET threshold and is there a test report available…
Part Number: UC1846 Hello:
How do I generate stable 10 kHz to 1 MegHz complementary PWMs from UC1846 or any other suitable controller without making a complete SMPS solution?
On board, we just want to have 1 chip controller that generates 2 PWMs with…
Part Number: UC1846-SP Other Parts Discussed in Thread: UC1846-EP Tool/software: Hello,
My customer has questions about the TI product line.
What is the difference between -SP products and -EP products? (ex. UC1846-SP, UC1846-EP)
Can '-EP' products…
Part Number: UC1846-SP Hello,
The UC1846-SP datasheet shows a pin for the gate drive voltage, VC. The absolute max ratings show the VC voltage should be no greater than 40V. Is there an operational minimum for this supply pin?
Can the gate drive output…
Part Number: UC1846-SP Other Parts Discussed in Thread: UC1526 1) When using an external sync, what type of signal is expected? Will a Square wave of 5V amplitude and 300KHz be sufficient?
2) What happens during start up, when an external sync is…
Part Number: UC1846 Other Parts Discussed in Thread: TLV3501 Hello:
I can make the TINA model work using UC1846 for a SEPIC converter but it is not giving correct results.
The grand scheme here is to explore how it will work with feedback and then…
Part Number: UC1846 What sort of current limiting, if any, is used on the internal 5.1-V reference regulator output (VREF) -- I assume this is an LDO -- is it using a brickwall or voltage foldback current limiting approach? The customer is concerned that…
