Part Number: TPS61378-Q1 Other Parts Discussed in Thread: TPS61178 , TPS61288 , TPS55340 Hello, we tested and validate the TPS61378 chip to have +15 / 18 Fdc from the +5Vdc.
But the part TPS61378 is not available from any sealer in Europe.
Is there another…
Part Number: TPS61378-Q1 Dear team
The customer used TPS61378QWRTERQ1, because the samples need to be transported to CN for production, the country of origin of the samples needs to be filled in when the samples are exported.
1. Can you help provide…
Part Number: TPS61378-Q1 Hi Team,
The TPS61378 datasheet states that the bootstrap capacitor is recommended to be 0.1uF to 1uF. Can you confirm that this is the nominal value of the capacitor placed for this pin?
If so, can you also confirm what the acceptable…
Part Number: TPS61378-Q1 12.6V to 15V, can only carry 300mA load at startup, normal load after startup,
Schematic as below:
PCB as below, 10 layer
When the load is increased to 400mA at startup, the input Waveform disconnect. VCCOUT, VO are abnormal. In…
Part Number: TPS61378-Q1 Hello, team.
Could you please advise, can PG pin of TPS61378 be either left floating (unconnected) or tied to GND if customer doesn't use this feature and has no ability to tie this pin up to Vout or Vin?
Thank you.
Part Number: TPS61378-Q1 Hi experts,
Do you have a test waveform of TPS61378-Q1 FREQ pin during device normal operation? Below is what we measured on customer’s board. The output voltage is normal but customer has question about the FREQ waveform…
Part Number: TPS61378-Q1 Hi, Is it possible to boost 3.3V to 5V with this device without entering the down-mode? because there is headroom on ISO- FET in certain condition and it reduces efficiency i want to know if this is possible.
Also please tell…
Part Number: TPS61378-Q1 Dear, Team
Could you please help review the schematic?
The spec is as follows : Vin = 6-8.3V, Vout = 14V, Iout(Max) = 1.14A, Efficiency 90%
