ABOUT DC-DC

i have a doubt for AS1340,what is Ioutmax?why? Any help will be apreciated !
 

Re: ABOUT DC-DC

it depends on Vout you want .

Quoteing datasheet

- 100mA @ 12V from 3.3V VIN
- 50mA @ 24V from 3.3V VIN
- 30mA @ 36V from 3.3V VIN
 

Re: ABOUT DC-DC

thanks for reply,its power constant output?if input -voltage is 7.2v,not 3.3v,what Ioutmax is it?
 

Re: ABOUT DC-DC

hi,
there are two general ways using this chipAS1340 as the datasheet poses, split supply and not.
That Vin in your application is 7.2V, which is above 5.5V ,it need to split supply.In the datasheet,there is a graph showing the relation between Iout and Vin,hope it be useful.
