Hi,
I am trying to understand more about switching regulator IC's and available current.
I was looking at a device MIC2605, which raised some questions. The datasheet says that the chip has a 40V/0.5A switch, and that the typical switch current limit is 0.5A / max 0.8A.
The datasheet talks about how to calculate the output voltage, but does not seem to describe how to determine the possible output current when the input / output voltage has been set.
Figure 2 of the datasheet shows a typical circuit, the input is 12V and the output is shown as 32V 30mA - but no reference to how that 32mA was derived.
The datasheet has a graph, switch current versus input voltage, but i do not understand the input voltages shown - 46 81 01 21 41 61 82 0.
Can anyone help me to understand how to calaculate the maximum output current of a switching regulator IC?
Thanks
