Step-Down DC-DC Converter
15 Watt TSI-15N Series
TSI-15N Series are step down converters whith a very high efficiency . By adopting a custom
multi chip module IC, it was possible to reduce the number of components drastically.
Herewith two goals, high reliability and low cost could be realized.
Features
- Ultra Small
- Easy to use ; SIP / DIP type
- Adjustable output range
- No Heat Sink required
- Long life, High reliability
- High efficiency (84 ~ 94 %)
- Operating Temp. -10°C ~ +70°C
- MTBF 1,000,000Hrs.
- Over-Current Protection
- Over-Temp. Protection
