Because of switch power supply, high working efficiency, and generally can achieve 80% above, therefore, in its output current choice, should be measured accurately or calculation of maximum absorption current electric equipment, in order to make the switch power supply Is adopted with high ratio of performance to price, usually output computation formula Is: Is = KIf type: Is--of switch power supply output current ratings; If-electrical equipment maximum absorption current; K-allowance coefficient, generally take 1.5 ~ 1.8;
Edit this paragraph 3.3 protection circuit
Switching power supply for design must be with the flow, heat, short circuit protection function etc, so in the design should be preferred protection function complete switch power supply module, and the protection circuit technology parameters should be and electrical equipment work characteristics match, in order to avoid damage or electrical equipment
