1. The regulator proposed to establish the input voltage by
soft-start, no plug and play, if the input voltage changes from
low voltage to high voltage abruptly, the regulator might be
damaged.
2. If the applications is high-voltage input, the regulator
must add an external capacitor C1(≤47μF/100V) to prevent
voltage spikes caused by damage to the module.
3. No parallel connection.
1. The input current amount of the back-grade regulator and
the pre-class load should be less than or equal the max load
current of the pre-class regulator.
2. If further ltering is required, please add components
as per the above circuit (We recommend not to add
components), if request, please make sure the capacitors C1
≤47μF, C2≤10μF more close to the back-grade regulator.
High voltage input, multiple outputs, with greater load
