Functional Descriptions

CV/CC mode control

The A2106V provides CV/CC function. The CV (constant voltage) function is implemented to deliver a regulated output voltage for the output terminal, and the CC (constant current) function is to limit output current to be a limited value to prevent the device damaged due to output short circuit or over current condition.

Soft Start function

The A2106V is composed of built-in internal soft start function to prevent a large surge current happening when during start-up period due to the surge current charging output filter capacitors.

Output Over-Voltage Protection

The A2106V provides output over-voltage protection function. When output over-voltage happens, the A2106V shuts down and recovers to normal state automatically if output over-voltage is released.

Output Short-Circuit Protection

The A2106V provides output short-circuit protection function. When output short happens, the A2106V shuts down and recovers to normal state automatically if output short-circuit is released.

Cable Compensation

The A2106V provides output cable compensation function. It's following with load, and the compensation voltage is 212mV when VISEN is 100mV.
