YLPTEC B1215S-1WR3

1W, fixed voltage input, isolated unregulated single output, with over-temperature protection and continuous output short-circuit protection, RoHS compliant. This series is specifically designed for on-board power systems requiring a voltage rail isolated from the input supply. Suitable for applications where the input supply voltage is relatively stable (voltage variation range ±10%Vin), isolation is required between input and output (isolation voltage ≤1500VDC), and output voltage regulation is not critical. Typical applications include purely digital circuits, general low-frequency analog circuits, relay driver circuits, and data switching circuits.

• Isolation voltage: 1500VDC/1min, 3000VDC/1s
• Low no-load power consumption: 0.025W (typical)
• Operating temperature range: -40℃~+85℃
• Efficiency up to 91%
• Output short-circuit protection: continuous short-circuit protection, auto-recovery
• International standard pinout
• Compact SIP package
• Low ripple/noise (20MHz bandwidth): 30mVₚ₋ₚ (typical)
• MTBF ≥ 3,500,000 Hrs

Suitable for applications where the input supply voltage is relatively stable (voltage variation range ±10% Vin), galvanic isolation is required between input and output (isolation voltage ≤1500 VDC), and output voltage regulation is not critical. Typical applications include pure digital circuits, general low-frequency analog circuits, relay driver circuits, data switching circuits, and similar use cases.
