Part Number: UCC2808-1 Other Parts Discussed in Thread: UCC2808-2 , Hi team,
Can you help comments the difference between UCC2808-1 and UCC2808-2? Is UVLO turn on and turn off threshold the only difference?
Also, UCC2808-1 PDIP package CAD symbol or PIN…
Part Number: UCC2808-1 In the d/s, the junction temp is 150degree in the Abs Maximum Ratings, but in the recommended operation conditions it specifies the 85degree.
1. I'm confused with junction temp. Which one we need to follow up
2. If junction…
Part Number: UCC2808-1 Other Parts Discussed in Thread: LM25037 Customer is developing the push-pull with UCC2808x series, but they found when duty cycle is higher than 46%, the waveform will become abnormal. Thus, trying to adjust the RT/CT ratio to adjust…
Part Number: UCC2808-1 Hi,
I am current using UCC2808-1 PWM controller in a DC to DC application. The max VDD for the part is 15VDC with recommended range of 13-14VDC. The part has an internal 14V zener to clamp the voltage. My input go slightly above…
Part Number: UCC2808-1 How to make PWM duty up to 50% with workaround solution?
How about to connect both pins of the FB and CS pin to Grounding pin and there is a capacitor on COMP? With this circuitry, is it possible the OUTA and OUTB can be output…
Part Number: UCC2808-1 Hi Team,
could you help to comments Difference of peak current and overcurrent comparator? we found two compactor on block diagram of UCC2808, but there is no description of them on datasheet.
Thanks very much.
Regards, Sunny
Part Number: UCC2808-1 Other Parts Discussed in Thread: LM5045 , LM5046 , UCC29002 I would like to use the UCC2808-1 push pull design as described in this webbench power design: webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=05EB8E641095661F
I'm having…
Part Number: UCC2808-2 Other Parts Discussed in Thread: UCC2808-1 Hi,
I use the chip UCC2808-2 and I would like to fix the duty cycle about ~40%. How to do it ?
I'm confused with COMP and CS pins functionnality. I read that "The CS pin is for duty-cycle…
Part Number: UCC2808-1 I think there is an error in the block diagram. There are two comparators tied to the Softstart line. One has threshold of VDD-1V but the softstart spec on pg 5 says the SS range is 0.5V to 4.0V. What is the correct threshold?
