Hi there,
I have tried making a small circuit using the LTC3122 and the application example on page 19 in the datasheet (http://cds.linear.com/docs/en/datasheet/3122fa.pdf), however, with a slightly larger coil. The circuit is supposed to source 833 mA @ 6V, but 70 mA is the max current I can draw from the circuit with a small servo motor or a resistive load. The voltage input is a couple of AA batteries.
How is the current limit controlled by the circuit, and why is the current draw so low before affecting the voltage?
Thanks in advance
