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

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.
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 effectiveness while using a 100-ohm bleeder also a 500-ohm bleeder can be used. 500-ohm bleeder will have an offset of 65mV.
