dc/dc step up converter

[simondid]

hey

so i'm looking for a dc/dc step up converter design which takes 3 to 6 volts and can output between 5 and 12 volts i need the design to be adjustable with a resistor.

that input to this converter is a pin called IPSOUT  from the C.h.i.p pro sbc witch has a 2.5 amp at up to 5v limit the pin is described as following https://docs.getchip.com/chip_pro.html#battery-charging-and-bts-pin

The Intelligent Power Select provides up to 2.5 amps at up to 5 volts, depending on power provided at CHG-IN or VBUS pins. If a 3.7V LiPo battery is the only source of power, IPSOUT will provide a bit less than 3.7 volts. In general, the voltage at IPSOUT is a bit less than voltage in, with a max voltage of 5 volts.

If you want to convert between 3V and 6V to 5V to 12V, then you'll need a DC-DC converter which can both step-up and step-down the voltage, since there's some overlap between the input and output voltages.

okay ya that makes sense

also, another question if you read the documentation do you read it like it can exceed 5 voltes?

a SEPIC converter will be able to meet your requirements.
