Part Number: UCC2806 We’ve been investigating some failures of units where we are seeing the boost converter MOSFETs fail. During this testing have noticed some abnormal turn on behavior. For reference, here is the implementation in the unit.

Part Number: UCC2806
Hi Everyone,
I want to use 4 UCC2806 with 90degrees phase shifted from each other.
Can you please tell me what will I see in CT pin when I enable external clock operation (connect RT to 5V).
Will I be able to add a voltage slope…
Part Number: UCC2806 Hi Everyone,
Is the following Possible:
UCC2806 with VIN = 12V and VC=5~7V?
What I'm really asking is the internal gate voltage for internal MOSFETs is VIN or is it 5V (the reference voltage)?
Part Number: UCC2806 Other Parts Discussed in Thread: UCC3806 I have a customer wanted to use the UCC2806M device in a HV application where the output is 1/2 the input voltage. This is for a design they need a prototype PCB done by end of this month, so…
I have discovered the problem. The UCC2806 internal error amp (opamp) has very low drive capability. I'm not sure how the reference circuits function, but with my output voltage regulating at 37V, maybe the instantaneous current requirement is during…
Other Parts Discussed in Thread: UCC2806 i am using ucc2806 in a push pull converter to get sine PWM output .
i am using 10% slope compensation on current sense pin
RT =15k, Ct=470 pf
Issue is i am unable to get below 10% duty cycle
Can someone help …
Part Number: UCC28C42 Other Parts Discussed in Thread: UCC2806 Hi Everyone,
I'm using the UCC28C42 Peak Current Mode Controller and I tie the RT/CT pin directly to the output of the external clock (it can handle the sink current of the controller).…
Other Parts Discussed in Thread: UCC2806 I'm using the UCC2806 in current-mode control for an H-bridge high power 300V isolated DC-DC converter. The voltage and current loops seem to be working fairly well. The current loop is limiting the current cycle…
In March 2013, you mentioned there is no spice model for the UCC2806. Have you created one since then? We would be very interested in a model for this part. If you don't have a model for the UCC2806, can you recommend an equivalent part which has a model…
