1 Watt
Single and Dual Output
Unregulated single inline package
With 80% efficiency, our 1 watt single and dual output DC-DC converter has 3000 Vdc input/output isolation. The design also features 1-watt unregulated output power and a miniature single-inline package (SIP).

INPUT
- 5V nominal input: 4.5 - 5.5 Vdc
- 12V nominal input: 10.8 - 13.2 Vdc
- 15V nominal input: 13.5 - 16.5 Vdc
- 24V nominal input: 21.6 - 26.4 Vdc
- Input Filter: Capacitor
OUTPUT
- Output Power: 1 watt max.
- Voltage Accuracy (Full Load and Nominal Vin): ±5%
- Minimum Load1: 10% fo FL
- Line Regulation LL to HL at Full Load: 1.3% or 1% of Vin
- Load Regulation (20% to 100% FL): 5V output ±10%, Others ±8%
- Ripple and Noise (20 MHz Bandwidth): 100mV p-p
- Temperature Coefficient: ±0.1%/°C, max.
- Short Circuit Protection: Short term
Notes
1The SPU1 Series requires a 10% minimum load on the output to maintain specified regulation. Operation under no-load condition will not damage these devices. However, they may not meet all listed specifications.
