Part Number: TPS40056
Hi TI expert
In TPS40056 controller datasheet page 12 Figure 4, The graphic shows VIN-VSW looks difficult to understand. When high side MOSFET is ON, VIN-VSW is supposed to be low, but it is high in this graphic. VIN-VSW=Vds of high…
HI Brayden:
In normal statues, the FB will follow soft start voltage raising, only see the soft start dc voltage is not helping for the root cause, as we mentioned , pls help show the SS PIN voltage waveform at start up.
and in the same time, pls compare…
Hi, Ambreesh-san,
Thank you for your support. When changing the switching frequency of TPS40055EVM to 100kHz under the condition that 12V was supplied to Vin, the phenomenon disappeared. However, the customer's Vin input voltage is 24V. Since the absolute…

Part Number: TPS40056 Dear, All
Customers are considering using TPS40056. They have questions about TPS40056's EA_REF pin. In the data sheet, the value of Input offset voltage of ERROR AMPLIFIER is described. However, its temperature characteristics…
Other Parts Discussed in Thread: TPS40056 , TPS40052 Is the offset in the current limit circuit lower or less variable in the TPS40056 compared to the TPS40052? I have been using the TPS40052 in production circuits for years and sometimes I get a board…
Hi,
The models (PSPICE and TINA-TI) on the web are encrypted and can only be used in the simulator in which they are released. If you need the unencrypted model to run in another simulator like Altium, please contact your local Field Applications Engineer…
