TLV62568: efficiency below 1mA load?

Hi Kevin,

Thanks for your question.

Since the efficiency and operation mode transitions depends on the operation conditions, can you please specify which VIN, VOUT are you interested in?

Thanks,

Stefano

Hi Stefano,

3.3VIN

1.8VOUT

30-100mA IOUT normal

200uA IOUT sleep 

Thanks,

Hi Kevin,

This is the efficiency plot evaluated on TLV62568EVM-789 for VIN =3.3V and VOUT = 1.8V.

The transition PFM/PWM depends heavily on working conditions and passive component variations.

For reference on the tested EVM the threshold was around 150mA.

Please ask again if you need further support.

Thanks,

Stefano
