Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi Li Yu
I test on TPS56837HEVM ,Vin=24V,Vo=15V, Io=3A. Probe on EVM the same as yours, the undershoot amplitude <2V. But I use a ×10 probe as I don't have a ×1 probe.
Can you please check with another probe?
Thank you
Part Number: TPS56837H Other Parts Discussed in Thread: TPS56837 Hello,
As a part of a power charging board I'm designing now I need to use the TPS56837H for converting 24v to 15v. .
Till now I considered working with TPS56837H since its data-sheet…
Part Number: TPS56837H Tool/software: Hello,
It is not clear from datasheet why were the R1,R2 resistors of the Vin voltage divider for the V-UVLO were chosen to be : R1=169k, R2=36.1k ?
How these values support Vin=16v to 28v while UVLO voltage are…
Hi Mark
I didn't find the max duty in the datasheet neither. But the Webench should be trust-worthy.
Will you consider TPS56837H or TPS56837HA ? There is an apps note about the UST-C application of TPS56837HA .
Thank you
I started the tests with 6 volts (circuit powered by a DC bench supply adjustable from 0 to 30V). with 6 volts the circuit turned on, in the feed back circuit my potentiometer was adjusted to 5K ohm, output signal with +- 6Volts, so I increased the input…
Hello Anna,
TPS56837 is designed for 0.6~13V output range, the internal loop design is based on this Vout range.
If you want to use higher Vout, we will release TPS56837H in Jan.2024, which supports 22Vout max, p2p with TPS56837. Please evaluate it. TPS56837HEVM…
Hello Marcin,
Thanks for evaluating TPS62933!
Sorry for my late reply, we were on Chinese New Year.
Please see my comments below.
1. Surely our device could support up to 22Vout_max, but thermal may be a problem if output power is high.
See this e2e p…
