Part Number: TPS62290-Q1 Customer found damages in the process of using TPS62290IDRVRQ1.
This IC has produced about 300 PCS in this project. At present, there are three boards with this problem. so, the failure rate = 1%
This batch of samples have…
The datasheet is clear about the maximum output current. Although getting higher output current at typical conditions may be possible I cannot recommend to use this device for a load current above the maximum specified. For higher output current I recommend…
Why using a dual DCDC converter for one output only? I would recommend to use a single DCDC converters instead, like TPS62290-Q1. It is smaller and can handle the same output power.
Anyway, if the second converter is not used I recommend to disable…
I would recommend to use the 1uH inductor. There is no need to reduce the inductor current ripple. You will get best performance regarding control and efficiency with this device if you stay with the recommended values.
If power good is not required…
Hi Gerald,
Thank you for the patience on this one. We have been working through using external DC/DC converters with the VDD6 rail on the TPS65381 device. Because the VDD6 switcher is a hysteretic mode converter it needs capacitance with ESR on the…
Anthony P Pham said: Taking a quick look, yes the TPS62290 looks like a good choice.
Thanks!
Anthony P Pham said: I can take a look at the BQ24030-Q1 portion of the schematic.
Do you have an email address to which I can send the schematic?
Alain,
That is my understanding. Attached are the schematics of the two boards used along with the ADC and DAC boards and the FPGA pattern generator/data capture card (TSW14J56EVM).

Jim

SM,
See "Dual Sync Source Mode" in section 2.4 of the attached document.
Attached is an example IF-to-RF conversion reference design using the DAC34SH84.
We do not have any example Xilinx reference design we can provide you with.
Regards,
Jim…
