We are looking for Iq of TPSM82823 which operate in 100% duty cycle design condition?

Did you have data on hand and can share with us?

Hi Ben,

The Iq is around 320uA in 100% mode.

Best regards,

Hi John,

Does this data is in device power save mode?

This Iq is too large and cannot meet customer's spec.

Ben

Hi Ben,

There was no load connected to the output for the measurement. The internal IQ in 100% mode is higher as the high side FET and more circuits are turned on.

However I see that the VOUT was used as pull up voltage for the PG on the EVM. There could be some leakage (33uA) on this path.

What is the customer spec for IQ in 100% mode? Usually the application runs in 100% mode close to the end of life of the battery, so this maybe only for a short time.

Best regards,

Varun
