APPLICATIONS
The K78UXX-500(L)
series
high
efficiency
Short circuit input power Vin=Nominal
Short circuit protection
Thermal shutdown
Switching frequency
Output current limit
Quiescent current
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.
