Part Number: TPS54228 Hi team,
My customer is designing the circuit of this device and have some questions about it.
In the datasheet, there is a table about the recommended component values.
If the output voltage is 1.8V or 3.3V, even if the customer…
Part Number: TPS54228 Hi team,
In this section, there is a fomula for the ajustable soft start function.
If the customer don't need a soft start and wants to use small cap for this, what will be the minimum value for it?
Also, if they use a small…
Part Number: TPS54228 Hi team,
Could you give me comment on following customer question? The customer looks for alternative bootstrap cap options due to EoL. Datasheet describes a 0.1uF must be connected, but de-rated value looks to be less than 0.1uF…

Part Number: TPS54228 Hi Experts,
My customer wants to estimate the efficiency with below condition but Webench says below.
Vin ; 5V
Vout : 3.3V
Iout : 1.1A
Ta = 85 degC
We need to estimate the efficiency. What is the problem?
