Part Number: TPS62147 Other Parts Discussed in Thread: TPS3899 Hi,
According to TPS62147 datasheet P.5, we can find PG threshold.
As the above table, MAX threshold voltage of PG High->Low is MAX 98%-3%=95%. If voltage is below 95% for an instant,…
Part Number: TPS62147 Other Parts Discussed in Thread: TPS62135 Team,
-Is it possible to use a TPS62147RGXR / TPS62148RGXR on an existing TPS62135RGXR PCB? All 3 devices have the same VQFN-HR package. The main difference is pin 4 (FB2 on x35 and AGND on…
Part Number: TPS62147 Hi,
The datasheet for the TPS62147 mentions in the layout guidelines (12.1) the following: "In case any of the digital inputsEN, FSEL or MODE need to be tied to the input supply voltageat VIN, the connection must be made directly…
Part Number: TPS62147 Hi, Team
My customer wants to know - for TPS62147, if Vout is added external 5V while no Vin, Is it OK?
Vin is connected with input caps and no other load.
We are afraid that TPS62147 internal circuit has issue in this condition, such…
Part Number: TPS62147 Dear Engineers,
I have one concern about inrush current on input.
I desinged the board and measured inrush current.
Then I found large current "about 50A" occurred...
(please refer to the picture attached. Blue is input…
Part Number: TPS62147 Hi, I need a buck converter for a board which has a VHF packet radio transceiver. I'm bucking from 14V to 5 V. The 5V feeds a 3.3V LDO which powers the transceiver.
The five volts also powers USB host, (500ma out), and is for…
Part Number: TPS62147 Hi,
In the datasheet of TPS62147 page 8 there is a schematic that display how to use the comonent in FSEL=low. But the value of CSS is different between the schematic and the table under it.
In the schematic the value is 3,3uF and…
Part Number: TPS62147 Hello,
It is an inquiry from my customer.
Can they use SP - CAP or OS - CON on the input / output side of TPS62147?
(Conditions to use:12V → 5V / 1A)
If you have recommended capacitors other than ceramic capacitors, please…
