Other Parts Discussed in Thread: TPS54040A Input Voltage: 23.5V to 32V with occasional transients to 42V
Nominal output voltage: 24V, dropout to 22V acceptable
Load: 0mA to 250mA
I have an application requiring an output with the conditions stated above…
Part Number: LM5165 Other Parts Discussed in Thread: TPS54040A , Dear TI-Team,
actually we are using the TPS54040A with a Slow Start. The current soft start time is 70ms with a 220nF capacitor. In the datasheet of the TPS54040A it says "The slow start capacitor…
Other Parts Discussed in Thread: TPS54040A Hello, all
Now we have one inquiry regarding low dropout operation on TPS54040A from our customer.
Please refer to the item below, and feedback us with your comment.
Now we are going to use this device for TM4C1294NCPDTI…
Hi Henry,
Good Day. Please see below the response of our customer to your reply. Thank you very much.
I clearly noted that “ we can use the same TPS54540 to generate a negative output with an Inverting buck-boost (IBB) topology".
The problem…
Other Parts Discussed in Thread: TPS54040A Hi all,
I have assembled (using the TI design tool) a TPS54040A-based switching circuit with 3.4-3.5V out. I have built two boards and checked all of the components and connections on them, and I am seeing the…
Hi,
I'm implementing a dc-dc convertor design that generates symmetrical +8 & -8Vdc from a dc input of +9 to +12V. Current is low (< 0.25A)
When I ran the Excel spreadsheet, I get values for R1 and R2 of 19K and 1K respectively. Are these values…
Other Parts Discussed in Thread: TPS54040A , LM25574 I need an inverting buck-boost power supply to convert 8-10 Volts in to -9 Volts out at 10-100 mA. I need to be able to sync the switcher at about 700 kHz. Board space is not a concern.
Both the TPS54040A…
Part Number: TPL0401A-10 Other Parts Discussed in Thread: TPS54040A I try to calculate R11& R7 by equation(24) & (25), but can't get right value in figure-9.
Please help, thank you.
