APPLICATIONS
The
K78xx-1000
Series
high
efficiency
switching regulators are ideally suited to replace
78xx linear regulators and are pin compatible.
The efficiency of up to 96% means that very little
energy is wasted as heat so there is no need for
any heat sinks with their additional space and
mounting costs.
