Part Number: UC1843 Other Parts Discussed in Thread: UCC28C43 Hi team,
The UC1843/5 can be shut down by two methods, may I ask the quiescent current of UC1843/5 in the shutdown mode?
Thanks in advance!
Regards,
Ivy
Part Number: UC1843 Other Parts Discussed in Thread: UC1844 , I have a power supply with first stage UC1843 for boost and second stage UC1844 for Flyback and the output. problem is on cold temp test, power supply has a delay of several seconds to start…
Part Number: UC1843-SP Other Parts Discussed in Thread: LM139AQML-SP Hi Team, We're almost certain but we need to confirm if the parts UC1843-SP and LM139AQML-SP are non SEL (Single Event Latch-up) sensitive due to their bipolar process. I've also seen…
Part Number: UC1843-SP Other Parts Discussed in Thread: TPS7H5001-SP Hello,
I have a question about the UC1843-SP. I am working through the datasheet and using the TINA TI simulation “slum213” for the buck converter 18V to 5V. I looked through the datasheet…

Hi Experts,
Good day. I am posting this concern on behalf of the customer.
Below is the customer's full transcript of the inquiry.
"I would like to use two UC1843 in multiphase operation and provide a current sharing thanks…
Hi Ken,
I think using four UC1843 devices to realize 4 phase work is OK if the driver capability of controller that generates sync signals is OK.
I think you also can use two interleaved buck controllers with synchronization feature to realize 4 phase…
Hi Teng,
Thank you.
The sync pulse, which is the external clock that I generate, is always there. So if I drive the RT/CT pin without the coupling cap, the UC1843 will always be able to output PWM since the external clock is always present on…
Part Number: UC1843 Other Parts Discussed in Thread: UC2843 , UC3843 , TL2843 , UCC28C43 Hi Team,
I have a customer that is looking for additional models for the UC1843. I see that we have a transient model posted on TI.com.
Do we have any additional…
