To get a trimmable output i.e. adjustable for accuracy in the circuit where exactly should the trimpot be put?

    Hi Andy,

    The trim pot needs to be placed in series with one of the resistors that forms the potential divider that senses the output voltage and feeds the divided down version of the output voltage to the error amplifier. Depending on the design the trim function maybe limited to say 10% of the output voltage nominal setpoint.

    Regards
