USB Interface
The USB interface forms the connection between the PC and
the evaluation system. It converts the commands from PC to
I
age (for the evaluation board (if jumper J1 is set to ADJ) and
makes possible to measure selected voltages and the input
current in the evaluation board. When LP5526 is used with
USB board and USB power is used, jumper J1 must be set to
5V setting to ensure sufficient power LP5526 boost converter.
However maximum boost output current is not achievable

when using USB power because of the limited current from
USB.
THE USB INTERFACE FIRMWARE
The USB interface checks for the firmware version of the USB
board when the evaluation software is started. If the firmware
needs updating, the software prompts you to allow automatic
update.
