The K78UXX-500(L) series high efficiency

switching regulators are ideally suited to replace

LM78xx linear regulators and are pin compatible. It

has ultra wide input voltage range ,the efficiency of

up to 95% means that very little energy is wasted

as heat so there is no need for any heatsinks with

their additional space and mounting costs.

Note:

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.

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 filtering 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.

Note:

1. The load shouldn't be less than 10%, and the output external capacitor should not be too large (recommend <10μF), otherwise ripple will increase

dramatically.

2.Operation under 10% load will not damage the converter; However, they may not meet all specification listed

3.All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.

4.In this datasheet, all the test methods of indications are based on corporate standards.
