Hi,
Please refer to the below application note for their differences.
Semiconductor and IC Package Thermal Metrics (Rev. D) (ti.com)
1. Based on this application note, in UC2843 case, I suggest to use Rtheta_jc_top.
2. You need to know VCC voltage and…
Part Number: UC1843-SP In the block diagram of the subject device, there is a "VREF GOOD" logic block shown that connects to the inverting input of a 3-OR gate. What are the rising and falling thresholds of this VREF Good block (monitoring VREF)…

Part Number: UC1843 Other Parts Discussed in Thread: TL494 Is there a UCx84x Current-Mode PWM Controller-like IC that brings out the error amplifier's non-inverting pin so that the user can supply his own reference to that pin? I would like to connect…
Part Number: UC1843 Hi team,
I understand that the device can be shutdown by pulling down the COMP voltage to lower than 2 diodes drops. But I wonder what is the specific voltage drop in this situation? because if I use a transistor to pull down the COMP…
