Part Number: TPS54295 Hi, team.
A frequency is about 700 kHz by 12Vin, 3.3Vout and 1A in Fig.16 of a data seat.
On the other hand, it's about 600 kHz by the same condition in Fig.18.
Are Fig.16 and 18 right?
Best Regards,
Part Number: TPS54295 Can someone help to explain the effect if TPS54295 soft-start pin is floating (not connected to the capacitor)?
Can the IC produce the required output?
Part Number: TPS54295 Hello.
I have used the TPS54295 in a board that digitizes the analog signal from a load cell and send it from a serial port. But testing the board's power supply I realized that measuring the feedback pin's voltage does the TPS54295…
Other Parts Discussed in Thread: TPS54295 Hi Team,
I am Khai Lee, FAE in TI Korea
TPS54295 has an internal regulator(Vreg5) which output is fixed to 5.5V and it is to generate reference voltages on feedback block.
However, what if VIN is lower…
Other Parts Discussed in Thread: TPS54295 Hi all, Would you mind if we ask TPS54295? <Our cutomer's requirement> 4～9Vin -> 3.3V/30mA (for DSP I/O) -> 1.2V/100mA（for DSP core） Our customer would like to always use PWM mode.(no ECO-mode) Of course, we understand…
Part Number: TPS54295 Hi all Would you mind if we ask TPS54295? <Question1> According to adding Cff capacitance, is it possible to decrease Vout's ripple voltage? (Is Cff capacitance effective to decrease Vout's ripple voltage?) <Question2> In case of…
Other Parts Discussed in Thread: TPS54295 Hi all Would you mind if we ask TPS54295? The datasheet shows ENx input resistance is TYP 450kohm. Is this resistance internal Pull-up or Pull-down? We need your help. Kind regard, Hirotaka Matsumoto
Other Parts Discussed in Thread: TPS54295 , TPS54528 Hi all Would you mind if we ask TPS54295 and TPS54528? How much is VREG5 when Vin is less than 5V? Will it be 5V? (VREG5 is typ 5.5V in case of 6 V < VIN < 18 V) We need your help always. Kind regards…
Hi John,
Thank you for your review on both project.
From my understanding, TPS54295 does not edit each component value on WEBENCH.
If possible, could you tell me how to edit each component value and re-simulate it.
Anyway one of project is…
Other Parts Discussed in Thread: TPS54295 Hi all Would you mind if we ask TPS54295? The datasheet shows that the transition point(from PWM mode to ECO mode) to the light load operation I Ox(LL) current can be estimated with Equation 1 with 700-kHz used…
