Other Parts Discussed in Thread: TPS54318 , TPS54618 Hello,
TPS54318 θJctop = 1°C/W TPS54618 θJctop = 46.09°C/W
Both package is QFN 3mm x 3mm.
In my understanding, thermal resistance in similar package has similar thermal resistance performance…
Hi Kevin,
If there is no PMIC solution, customer wants to use attached TI Switching Regulator Power Proposal. (see attached.)
But those parts are too heavy to use customer's solution, so she wants to get new proposal as below table.
Could you…
Other Parts Discussed in Thread: TPS54618 Hello!
We are experiencing an issue with the TPS54618RTE voltage reference. According to datasheet it equals 0.799V, but on our board it equals 0.49-0.5V (on VSENSE pin). Output voltage in fact equals output…
Other Parts Discussed in Thread: TPS53355A , TPS548A20 , TPS53515 , TPS53513 , TPS54618 , TPS54418 , TPS54218 Hello,
customer request MOS parameters typical value as below in order to calculate power loss. Could we provide that to customer? thank you…
Other Parts Discussed in Thread: TPS54618-Q1 , TPS62420 Hello,
For the purpose of failure rate calculations (as per IEC TR 62380), I need the transistor count for the ICs. An approximate is ok (such as "between 100 and 200").
The chips I'm interested…
Hello Onur,
You can use our DPPM/FIT/MTBF estimator tool on ti.com to determine the expected lifetime of any TI device, including TPS54678.
It should not matter in what condition you are using it in if you follow the recommended operating conditions…
For DCAP2 use TPS54627 but it is 2% accuracy
For current mode control TPS54618 or TPS54678 is 1% accuracy.
For voltage mode contrl TPS54610 is bettr than 1% accuracy. It is specified at 1% but the actual characterization data was 0.75% if I remember…
Other Parts Discussed in Thread: TPS54061 , TPS54622 , TPS54618 , TPS5430 What happens during a shorted output? I see current limit on the high driver but no current sense on low driver. Because VOUT is zero and the higher driver can only see the current…
Other Parts Discussed in Thread: TPS54218 , TPS54418 , TPS54618 Hi,
As all you know designing buck converter with Vin, Vout, Iout ( with %25 to %50 ripple approximation ) datas is not a big deal.
But I don't have any satisfactory solution if there…
Other Parts Discussed in Thread: TPS54618 , TPS54478 , TPS54218 Hi,
We are experiencing some issues with the TPS54418RTET on some of our units.
Configuration:
Vin=5V
Vout=1.8V
Load=~40mA
The regulator output voltage is correct, but the duty…
