Hi Harry,
Could you measure the time interval before first SW pulses and last SW pulses?
I would expect to be around 30ms. The SS end of TPS56837 is when Vss reaches 900mV. The SS time calculated with equation is when Vss reaches 600mV, as introduced…
Part Number: TPS56837 Hi
Howcome theres a limit on the recommended capacitance on the output from TPS56837 according to datasheet (220uF)?
If this is a hard limit, then this can become a problem, if the converter is driving an unknown circuit, with an…
Part Number: TPS56837 Hi
The circuit diagram was designed with the following specifications.
-spec-
input: 10.5~16.8V
OutputL 5V 8A
Please review it.
Thanks
Part Number: TPS56837 Hi team,
If the PG terminal is not used, is it okay to leave it open?
The datasheet mentioned "recommends a pullup resistor of 100kΩ to pull the PG pin up to 5V voltage" . How is it In case when PG terminal is not used…
Hello Ali,
I have sent you PCB file on 12/15, have you received it?
Thanks for sharing me the web link. It's a new application to me.
Could you share more application details? I don't know where is 'big capacitor' that you said. If you…
Part Number: TPS56837 Hi team,
May I know how I estimate Tj by using effective RθJa? Based on the Tj calculation in spra953c.pdf, calculated Tj exceeds absolute maximum rating of Tj of TPS56837.
Customer's use case:
Vin: 24V
Vout: 12V
Iout…
Part Number: TPS56837 Hello team,
I would like to set the switching frequency of TPS56837RPAR to 800kHz and ILIM=7.2A. According to datasheet Table 6-1. MODE Pin Setting, 102kΩ is required. Is there no problem with this combination of 100kΩ + 2kΩ resistors…
Part Number: TPS56837 Hello team,
My customer would like to use TPS56837 with 24Vin -> 12V / 4A output. But this device is designed for output up to 13V. Is it safe to use in 12Vout configuration?
I think the minimum ON time and minimum OFF time for…
Part Number: TPS56837 According to TPS56837 datasheet, the output voltage range is 0.6-13V. What is the reason why the maximum output voltage is limited to 13V?
If the load current is small, can the maximum output voltage exceed 13V?
