Hi Sir,
Recently, we will choose the LTC3892 Dual voltage output to design in.
Because our CPU have two types one is NA the other is AL, both different are the input voltate. one is 5V and other is 12V.
The LTC3892 datasheet at 21 pages said : "For the LTC3892 and LTC3892-2, channel 1 (Vout1) has the option to be programmed to a fixed 5V or 3.3V output through control of the VPRG1 pin"
my question is :
1. The Channel 2 (Vout2) same with channel 1,both can fixed 5V right ?
2. we need Channel 2 (Vout2) can output two voltage. one is 5V and the other is 12V。
The Channel 2 I want to design two output voltage. Can I design two circuits outside of FB2 pin, one without external resistor for voltage divider (5V) and the other with external resistor for voltage divider (12V)?
3. Do you need some schematic for you reference?
if you have any questions please feel free to let me know. Thanks.
Sincerely,
Will.
