FUNCTION DESCRIPTION

The changes of output load can cause the output voltage changes. The changes can be sensed by FB pin.

The output of error amplifier controlling output duty circle makes the output stable.

The P1696 incorporates an over current protection internally. Once the output is in overcurrent, power

transistor must be turned off immediately. In that case, the power transistor will not be damaged by the excessive

current.

If over-load or short-circuit condition happens, the oscillation frequency will be reduced, which make the

power transistor bears less heat, so the power transistor is protected from damage.
