I'm looking for a cost efficient way to create +/- 5.5v and 25.6v from a 12VDC wall wart supply. The product I'm working on will probably use a DC wall wart so I need a solution that will work with that.
I need these voltages to drive the GWTS80MNFG1E by Solomon goldentek display. The 5.5v is supplied for the display driver chip while the 25.6v is used to drive the backlight. There is also 3.3v and gnd to be connected but I already have those on the dev kit I'm using along with 12v and 5v.
According to the datasheet max current draw should be 80mA for the 5.5v supply and the backlight current should be around 75mA at 25.6v. Max current draw for the 3.3v supply is listed as 50mA.
Ideally I'd like to breadboard the solution so I can test the display before designing a board.
Thanks for helping! B
EDIT: I decided on the TPS65132 by TI which I'll power using the 5V on my board. For the LED driver I'm going to try using FAN5333 (not sure yet if I will be able to drive the 3 strings of 8 LEDs each with each string wired in parallel to the other one...)
