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…
Part Number: UC1843 Datasheet [SLUS223E –APRIL 1997–REVISED JANUARY 2017] quotes UVLO values listed against the various part numbers, but I cannot tell which row corresponds to the UC1843. The row titles are ;
Row-1 = UCx842/4 UC184x and UC284x.
Row…

Part Number: UC1843-SP Other Parts Discussed in Thread: UC1845 , UC1843 , , UC1845-SP Hi Sir,
I wanted to use space grade PWM controller for forward converter with current mode control.
There are many space grade ICs available like: UC1843, UC1845…
Hey Nerea,
The frequency you stated won't harm the UC1843, but it may cause issues with the functionality of the device while the frequency is 625 kHz.
Operating outside of the recommended operating conditions (625 kHz) will make it such that the…
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: UCC27611 Other Parts Discussed in Thread: UC1843 , Hi,
Can I drive the UCC27611 GaN Gate Driver's IN+ pin with a 12 volt output from a UC1843 PWM controller? I would connect the UCC27611 IN- pin to GND when doing this.
The UCC27611…
