Efficiency up to 96%
Temperature range: -40°C ~ +85°C
No heat sink required
Pin-out compatible with LM78XX linears
Short circuit protection, Thermal shutdown
Low ripple and noise
SIP package
Industry standard pinout
MTBF>2,000,000 hours
The K78xx-500 series converters can also
be used to convert a positive voltage into
a negative voltage.
Only two extra capacitors are required.
Input voltage range can be lower than the
output voltage for higher output voltages
RoHS Compliance |
K78xx-500 series switching
regulators are ideal replacement for K78xx
linear regulators and LDOs. 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. They are widely used in
industrial control, instrumentation, and electric
power applications. |
