Part Number: TPS65261 could you send me an either spice model for TINA, or LTSPICE?
The encrypted model is not easy to use. I heavily use LTSpice. Tina model is also okay.
Thanks.
Part Number: TPS65261-1 Hello,
My problem is that the TPS65261-1 is not starting up.
In the datasheet is specified that Vin is possible between 4.5V and 18V.
I use 4.8V. In the datasheet is specified that the LDO of V7V provides 6.3V .. but how is that…
Part Number: TPS65261 Would it be possible to disable hiccup mode for the TPS65261 by lowering SS voltage or toggling EN within 256 switching cycles?
If not, are there other means of disabling hiccup mode?
Otherwise, is there a triple buck available without…
Hello Hao,
Thank you for comment.
The last attached waveform is CH1 is VCC, CH2 is VOUT1, CH3 is VPUT2 and CH4 is VOUT3.
While VCC is forced, I move the jumper of EN3 from Low to High. EN1 and EN2 are tied to VCC.
ENx conditions are same of your conditions…
Part Number: TPS65261 Other Parts Discussed in Thread: TPS65251 , Hi team,
I got a question about delayed start-up for TPS65261. Can I use a small ceramic capacitor from the EN pin to ground (not use SS pin). Since I saw it on TPS65251's deatasheet. Does…
Part Number: TPS65261 Hi team,
My customer wants to ask about power up/down sequence. They want to use the following power up/down sequence.
Power up:Buck1→Buck2→Buck3 Power down: Buck1, Buck2 and Buck3 simultaneously
To acieve above sequence…
Part Number: TPS65261 I am trying to connect the compensation components to TPS65261.
Datasheet
On page 27, under the title "9.2.2.4 Loop Compensation", it gives the formulas to calculate the resistor and capacitor values.
I wrote the following…
Part Number: TPS65261-1 Hi
My current customer is using the TPS65261-1.
There are a lot of field defects in the product and we are looking for the cause of the problem.
Bad phenomenon: LX2 and PGND2 are short-circuited.
Confirmation request
1) In the…
Part Number: TPS65261-1 Hi team.
Customer did test as the below.
1. Initial condition
Input voltage : 12V
output voltage : 0.85V(no Load)
2. Test content
Duty check(@13.2 Vin) : 9.2%
Increase input voltate (15.6Vin) -> Onput voltate increase 0.93…
