Part Number: UCC24612 Other Parts Discussed in Thread: UCC24624 Some FET has a 4th pin, the source sense (SS) pin. in normal driver IC, the SS pin is connected to driver DC ground. but i am not sure which pin of UCC24612 is DC ground. in full bridge rectification…
Part Number: UCC24612 Other Parts Discussed in Thread: TIDA-010015 Hello Sir/Ma'am,
I'm trying to implement the reference design of TIDA-010015 through PSpice for TI software. But meanwhile I'm facing problem with placing of UCC24612…
Part Number: UCC24612 Other Parts Discussed in Thread: UCC38C40 , Hello everyone,
The problem is in the operation of the synchronous controlled rectifier using the IC UCC24612. The operating point is at 75V dc input and 12V output. The topology is flyback…
Part Number: UCC24612 Other Parts Discussed in Thread: UCC28600 , Hi,
The customer used UCC28600 to make a quasi-resonant flyback switching power supply, and UCC24612 to make a secondary side synchronous rectification control.
The problem now is that the…
Hello Dave,
Thank you for the new waveforms and additional information. In screenshots 1 and 2, you can clearly see reverse current peaks of about 10Apk at the moment when the SR FET turns off. The reverse currents are not clear in screenshot 3 because…
Part Number: UCC24624 Other Parts Discussed in Thread: UCC24612 , I would like to replace my full bridge 4 diodes rectifier with FET with SR controller. I realized that TI has UCC24624 and UCC24612.
Can I use them?
Is it correct that UCC24624 (dual channel…
Part Number: UCC24612
The purple waveform in the figure refers to the drive waveform provided by the UCC24612, while the yellow waveform refers to the voltage across the DS of the phase-shifted full-bridge secondary side MOSFET. Is this phenomenon due…
Part Number: UCC24612 I want to use this part for Buck converter application to replace freewheeling diode with a synchronous mosfet. do U see any shoot through issue with this type of application?
The input to buck is ~230VDC and output is 24VDC@8A.…
