WRN78XX-500 Series
WIDE INPUT,NON-ISOLATED REGULATED SINGLE OUTPUT SIP3 DC/DC CONVERTER
FEATURES
◆RoHS compliant
◆Efficiency up to 96%
◆SIP Package
◆Wide temperature range:-40°C to 85°C
◆Short circuit protection,Thermal Shutdown
◆No heatsink required
◆ Low ripple and noise
◆ Industry standard pinout
◆MTBF>2,000,000 hours
◆Only two extra capacitors are required
◆ Input voltage range can be lower than the
output voltage for higher output voltages
◆ The WRN78xx-500 Series converters
can also be used to convert a positive
voltage into a negative voltage
