LME0305SC
Isolated 0.25W Single Output DC/DC Converter
FEATURES
RoHS compliant
UL 94V-0 package material
No heatsink required
Industry standard pinout
1kVDC isolation
Internal SMD construction
Fully encapsulated with toroidal
magnetics
No external components required
No electrolytic or tantalum capacitors
DESCRIPTION
The LME0305SC is optimized for low-power
applications and is ideally suited to generating a
negative supply where only a positive rail exists.

APPLICATION NOTES
Minimum Load
The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage
range. Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically
double the specified output voltage if the output load falls to less than 5%.
1. See derating graph.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
