Part Number: TPS548B28 Hello,
We are planning to use the TPS548B28 switcher for a new design.
Pin# 20 is the output pin and is only 0.35mm wide. I'm sure I'm not understanding something but how is such a narrow width supposed to be able to deliver up…
Part Number: TPS548B28 Hi team,
Could you provide the dead-time information for my customer's internal design tool developing? Thanks!
Best regards, Sam Ting
Part Number: TPS548B28 Hi Team,
The customer reports a transient issue, and need to reduce overshoot and undershoot. In addition to increasing the output capacitance, how to adjust Cff or other parameters to reduce overshoot and undershoot?

Part Number: TPS548B28 Hi team, I have a question about how TPS548B28 soft start work.
If use internal reference voltage, the constant current keep charging soft start capacitor Css until the voltage of SS/REFIN pin arrive internal reference voltage 0…
Part Number: TPS548B28 Other Parts Discussed in Thread: TPS54JB20 Hi,
I failed to create a design with WEBENCH for TPS548B28, the specifications are:
Vin: 6 to 9 V; Vout: 5V; Iout: 15A
It seems there are no inductor candidate for this design specifications…
Part Number: TPS548B28 Hi,
My customer is planning to design heatsink for this component because of their high pre-heat and power dissipation.
What’s the maximum sustainable force of this package? They need this information for heatsink design. …
Part Number: TPS548B28 Hi team, here is a technical question might want your help.
When input VIN is12V, EN= 0V, e PG signal 0.89V? (PG pull-up to 3.3V, pull-up resistor 10K). Is this phenomenon proper? Or if there is any possibility that something is wrongly…
Part Number: TPS548B28 Hi, team
In TPS548B28 datasheet, the recommended maximum peak inductor current is 35A, is this value a calculated result? if yes, could you give me the formula?
Best Regards,
