Hii Team, Do Digital POL devices like TDA3860/ 740 devices work without a bleeder resistor on the output without affecting the operating system? Thank you for your help. Regards, Vikas
Hi Nidhi, Thanks for reaching out to Volt.Tech Engineering Community. If I understand right you need to program the data flash of the device just right?

Hi Nidhi,
Thanks for reaching out to Volt.Tech Engineering Community.
If I understand right you need to program the data flash of the device just right?
The data flash can be written in both ways, by Renesas Flash Programmer, or by self-programming (by the software running on the device).
To program only the data flash with Renesas Flash Programmer, the file used to program the device would require to hold only data for the data flash address range. A. srec,. hex, or. bin file can be used with RFP to give the data to be programmed into the flash.

Hello@vikas, It's always recommended to use a bleeder of 100 ohms. Vout of the part has an offset of around 250mV due to a leakage in no-load condition. The 100-ohm bleeder will pull it down. If there's no issue with 250mV offset the part can be used without bleeder also. If there's a concern with eRead more
Hellovikas Nagpal,
It’s always recommended to use a bleeder of 100 ohms.

The 100-ohm bleeder will pull it down.
If there’s no issue with 250mV offset the part can be used without bleeder also.
If there’s a concern with effectiveness while using a 100-ohm bleeder also a 500-ohm bleeder can be used. 500-ohm bleeder will have an offset of 65mV.
