Part Number: TPS40077
Dear team
There is a good news that we design in TPS40077(U91) in customer's new project.
Could you help to review the Layout?

The schematic looks better now.
Looking at the compensation spreadsheet, I had to change the part number to TPS40077, and after doing do, I noticed that the phase margin at the L-C resonance is very low. Looking into why, I can see a couple…

Part Number: TPS40077 Dear team
There is a good news that we design in TPS40077 in customer's new project.
The spec of customer's application is Vin=24V,Vo=12V,Io=12.5A
I refer the schematic from user's guide of TPS40077EVM-001.
Because of…
Part Number: TPS40077 Hi
I use TPS40077 to output 15V, 10A. Din is 24V. Schematic diagram as below. I control it only can output up to 13.5V. Please help review it. Thanks.
Part Number: TPS40077 I am testing the design that was provided by our contractor of the TPS40077.
The input is 6.5V to 9.5V and is supposed to give 3.3V output, but I am only getting 1V.
Other Parts Discussed in Thread: TPS40077 Hi Team, The datasheet shows 470uF electrolytic capacitor is required to maintain the voltage on the input rail. However there isn't 470uF input capacitor in "EXPAMPLE APPLICATIONS(page.34-36)", it shows 22uFx2 only…
Hi Team, Could you tell me the following threshold voltage of VSS_H and VSS_L when short-circuit protection occur? (datasheet page.19)
My customer wants to know it to calculate the duration of "7 soft-start cycles". Your support would be appreciated…
Other Parts Discussed in Thread: TPS40077 Hi Team,
My customer considers to use RT=150kΩ(Fsw=300kHz) and RKFF=110kΩ for TPS40077. Is there MIN/MAX value of UVLO(on) threshold voltage under above condition?
I believe there is no MIN/MAX value…
