Part Number: UCC25660 Hi team,
I am considering an LLC circuit at high frequency.
The frequency increases at startup, but what is the maximum frequency?
Best regards,
William,
Can you please clarify what exactly do you mean by power limit feature? What is the reaction you'd like the IC to have when the limit is reached?
Like Mike mentioned, there is over load protection feature leveraging VFB voltage. Not sure…
Part Number: UCC25660 Hi,
I am planning to use UCC25660 IC in low voltage input application. Where the specifications are Vin=48V; Vout=24V/30A.
In the datasheet the efficiency curve is given for HV input conditions. Does the efficiency similar to the…
Part Number: UCC25660 Can someone please explain to me what to do with the following information.
If I enter Qe in cell C56 with 0.37, the LLC Gain curve is OK, but in cell C102 it says "CAUTION. Update Cell C57 with new Qe"
If, on the other…
Part Number: UCC25660 Dear team, I am writing to inquire about a specific aspect of the UCC25660 LLC controller that we are currently using in our system. We employ the UCC25660 in a half-bridge LLC configuration with a fixed input voltage of 360VDC and…
Part Number: UCC25660 Other Parts Discussed in Thread: UCC28070 I'm looking at using the UCC25660 in a custom DC-DC application to produce 34V 1300W. In this application a PFC is required, and I have selected the UCC28070 PFC controller.
Are there…
Part Number: UCC25660 Hi, I'm trying to understand the various (VLLA-VLLB) options.. Why would someone want the HFBurstEntry threshold to be lower than the LFBurstEntry threshold? It seems it will never go into HF burst mode with (VLLA-VLLB) less than…
Part Number: UCC25660 Hi,
I'm considering TI's LLC controller as a replacement for the SSC3S902. https://www.semicon.sanken-ele.co.jp/sk_content/ssc3s900_ds_en.pdf
The following features are required. ・Automatic Dead Time Adjustment ・Capacitive Mode…
Part Number: UCC25660 Hello, we have designed a 400W supply using the UCC256601. The power supply is not able to start under load, even with only a 50W load. It just keeps retrying at second interval. Any idea what could be the problem here?
Any help…
