Hi,
I'm use **broken link removed**.
I use input 3V from battery and use 5V at output.
The problem is, my circuit use 5V, >100mA but the device only can supply up to 100mA. I tried to boost current, same as boost current for voltage regulator 78XX using TIP2955, but it fail produce 5V output.
This will not boost current, as the transformer used is meant for 100mA only. It is not a Linear Regulator but a DC/DC converter. You are trying implement the linear regulator's procedure on a different type of circuit. You have to select a higher current model converter to get more current.

What type of transformer?
An iron core or Ferrite core?
An iron core will not work because of High Frequency used in DC/DC converter.
A Ferrite core, YES, this will but to increase current -> A bigger transformer and proper related circuitry.
