Pin 33, IOUT

Output current sensing. The measurement of this pin voltage allows implementation of the

following functions:



Load feed-forward. The input current reference is modified proportionally to the load, in

order to provide a faster response versus the load transient.



Channel power management. Each channel can be enabled or disabled based on the

output current level. For example, up to 30% of the load, only one channel may be

enabled, from 30% to 60% of the load, two configuration channels can be selected and

at full load all channels may be activated.

Pin 34, VOUT

Output voltage sensing. This feedback input is connected via a voltage divider to the boost

output voltage. This measurement allows implementation of the following functions:



Output voltage regulation



Overvoltage protection

In Figure 5 the block scheme of the VIN, IOUT and VOUT is shown.
