Part Number: UCC25660 Tool/software: We would like to design a DC power supply for our hi-fi active speaker with input 220V and output 36V300W, requiring load variation of 10W-300W, low ripple and low noise. Which circuit structure and chip can meet…
Part Number: UCC25660 Other Parts Discussed in Thread: UCC24624 Tool/software: In the previous forum questions, UCC24624 is recommended for the secondary side LLC controller compatible with UCC24660 primary side LLC controller. How two of the controller…
Hello,
I reviewed the excel tool for the 1 kW design.
What you have selected for RLLupper and RLLlower is not within +/-5 % of what is recommended.
What you have selected for R25 is not within +/- 5%.
Please remember when using the excel design to use…
Part Number: UCC25660 Other Parts Discussed in Thread: UCC25600 Dear team,
Below are the details of the circuit I require: Find below image, 1. Input is the sine wave, 2. When the voltage rise above threshold A, output must be high. 3. When the voltage fal…
Part Number: UCC25660
Dear team,
Below are the details of the circuit I require: Find below image, 1. Input is the sine wave, 2. When the voltage rise above threshold A, output must be high. 3. When the voltage falls below threshold B, output must be low…
Part Number: UCC25660 Hi team,
We employ the UCC25660 in a half-bridge LLC configuration with a fixed input voltage of 360VDC and an output voltage of 600VDC. The capacitance of the secondary winding of the transformer is estimated to be within the range…
Part Number: UCC25660 Hi TI team, I have a small query regarding any possible failure mode of UCC256603 when the external Aux supply is not available but High voltage is applied at HS (split capacitor half voltage) and sense voltage at BLK pin.
Part Number: UCC25660 Tool/software: Hi,
Q1. The datasheet describes "HV startup" on pages 33 and 55. What process is required to disable HV startup on UCC256601?
Q2. Please tell me how to calculate FBreplica listed on the TSET pin.
Specifically…
