addition, confirmation following points necessary actual circuit. output ON/OFF control operates effects. there malfunction ambient temperature change each device exogenous noises? Points Remember Pattern Designing Transient large current flows terminal pin), recommend input capacitor should 3000F above. addition, terminals input capacitor should near terminal pin) terminal pin). Large current flows terminal pin) IC1, SWOUT terminal pin), C2A. wiring should thick short. terminal pin) feedback terminal from output voltage. should near output capacitor C2A.
purpose ensuring stability oscillation, capacitor should inserted between terminal pin) terminal pin). absolute maximum rated voltage terminal pin) absolute maximum rated voltage terminal pin) within range according output voltage type. When voltage equal higher than rated value applied terminal pin) terminal pin) some cases such abnormal test, protection measures like inserting fuses should taken. built-in over-heat protection function prevent circuit from overheat state caused transient temperature rise, function prevent from abnormal caused sudden heat generation. addition, reliability over-heat protection function guarantee.
