Hi Renan,

The startup supply current of UC3854A and UC3854B is 300uA. But I didn't find this information of UC3854.

I am checking it and will get back to you soon.

Regards,

Teng

Renan,

The UC3854 has a standby current 1.5mA max (2.0mA typical) and an operating current of 16mA max (10mA) typical.

This is measured with a Vcc of 18V and a oscillator frequency of 70kHz.

Regards

John
