15 Out-OK open-collector signal indicating boost function status

1 Railway applications (compatible with EN50155 for rugged coach environments)

2 Industrial rugged power supply systems

3 Expanding input voltage range of DC-DC converters (e.g.,110IMY15/70 series)

4 Battery-driven mobile applications (resistant to voltage surges/transients)

5 Systems needing predefined interruption time (via external Chu capacitor)

6 Environments where input voltage may exceed output (direct feed-forward when Vi>VoB tr)

7 High-efficiency power solutions requiring adjustable output voltage

8 RoHS-compliant component integration for long-term reliability

1 Do not open the converter (no user-serviceable parts)

2 Install external fuse in non-earthed input line (e.g., Littlefuse218,10A/250VAC fast)

3 Ensure case temperature ≤100°C (enclosed) or ≤120°C (open-frame)

4 Ambient temp range: -40°C to70°C during operation

5 Open-frame models: Clean only with isopropyl alcohol+deionized water (1:1) at room temp

6 Not for nuclear/medical/life support critical applications

7 Parallel/series operation is not allowed

8 Chu capacitor must be rated to adjusted VoB tr voltage

9 Avoid output short circuits (not short-circuit proof)

10 Follow pin allocation strictly; use 1.4mm PCB holes for 1mm pins
