Part Number: TPS62933EVM Hi team,
My customer is trying to operate this EVM at 2MHz. They have made the following changes- R7 = 10k, JP1 installed, R4= 31.6k.
The EVM is still operating at 500kHz. What else do they need to do to have it operate at 2MHz…
Hi Gui He,
I found the problem: there's a low impedence path between the +5V rail and the +3.3V output of TPS62933EVM.
Attached you can see the part of schematic where this happens: D1 connected on R pin of THVD1406DR transceiver creates the path between…
Hi Gao,
1. Today I did bench test on TPS62933EVM using your component values: Rfb: 10K/178K (15Vout); L: 6.8uH; RT floating (500kHz); Cout: 2x100uF electrolytic capacitor + 8x22uF MLCC (effective capacitance 4uF per cap with 15V DC bias).
I could reproduce…
Hi Robert,
I'm the MVB team AE who supports TPS62933/2. As you care about TPS6293x low drop-out application, I have below TPS62933EVM test results for your reference, condition: 15Vin-Set15Vout.
