Part Number: UC2843 Hi,
I'm trying to simulate Flyback converter's FRA in PSpice for TI
The schematic as below
But I got error like this
Can anyone help?
Part Number: UC2843
I am designing a Floating Buck converter(Power Switch connected in negative DC input side, positive rail directly connected to the battery) for 52V/15A Battery Charger using UC2843, Battery Should charge at 15A in CC Mode until the…
Part Number: UC2843 Hi Team,
Customer use UC2843 in flyback and want to shut down the output through pulling down comp voltage, but they found when pulling it to ~0.5V, some parts have no PWM output but some parts have.
So want to check with you below…
Part Number: UC2843 Hi Team,
Here are two questions when use UC2843 in flyback topology. 48V ( 34V-60V) input, 9.5V/2A output.
1. we found when Ton is large, there are two steps on OUT pin. Please kindly check the reason and if the 2rd step will drops…
Part Number: UC2843 Other Parts Discussed in Thread: UCC2895 Dear Team,
We find the UCC2895 PSFB's Vds(CH2 green) noise will affect UC2843 Buck's Pin4 triangle waveform(CH1 yellow), so the Buck duty will be abnormal
As you can see waveforms, when…
Part Number: UC2843A-Q1 Other Parts Discussed in Thread: UC2843 Hi, anybody have the any reference Tina Model / ref schematic for UC2843 which can take DC input of 75-150V and convert it to 14V, 10A.
Part Number: UC2843 Other Parts Discussed in Thread: TL431 , UCC28C45 Hello,
There 4 channels to drive 4 different colors LED. AL8862 (Diodes Co.) is used to drive LEDs with PWM dimming technology (PWM generation with ATMEGA328 Microchip). And on the power…
Part Number: UC2843 Dear TI-er
My customer have EMI issue.
UC2843 is occured to EMI issue in the board.
Normal case is from 95kHz to 96kHz frequency.
Worst case is from 100kHz to 105kHz frequency.
How I correct it ?
plz help me.
Part Number: UC2843 Hi team,
Could you please check what is the maximum OUTPUT pin high-level output voltage and what is the absolute maximum voltage rating for OUTPUT? Datasheet only specified the typical High-level output voltage?
Many thanks.
Best…
