Hi
Can someone Please help.Or elec_mech if you can please help!Thanks.
The schmatic i enclosed has a 5V output.I need a 9V ouput and a 3.3V output.Got this from TI.
I want to use this circuit to boost the output at the voltages above.
There will be two separate outputs using two separate converters.
1.I need to know at what FQ is the switching circuit set at in the enclosed schmatic. this set the Mosfet to ture on/off.They state to have it set to 300KHZ to 2MHZ.
2.What schottky diode are they using in this circuit at 3A.
3 The voltage input i need to use is 1.2 and 3.6 for each separate circuit.
But i don't know how to set the input voltage as they suggested in the
Design notes on page 10 in the Datasheet.
4. I will also need to change the voltage divider resistors for the two voltage outputs that i need to use.
