regulatedisolatedembedded

Overview
The IRT40 is an isolated DC-DC converter module that converts a 9–36V DC input to a regulated isolated 12V output up to 40W. It is intended for industrial and embedded applications that require a compact, efficient and protected isolated 12V supply.

Key features

• Isolated DC-DC converter module delivering up to 40W
• Wide input voltage range: 9V to 36V DC
• Regulated isolated 12V output (12V @ 3.3A)
• Low inrush current for controlled startup
• High-frequency ZVS topology for consistent efficiency

Protections and performance

• Output over-current protection (OCP), output over-voltage protection (OVP)
• Short-circuit protection and thermal protection
• Ripple and noise typically less than 120 mV
• Efficiency up to 90% at full load (some product literature cites up to ~95% in specific conditions)

Certifications

• CE
• FCC

Applications

• Industrial controllers and automation subsystems
• Communications equipment and embedded systems
• Vehicle electronics and battery-powered systems
• Any application requiring an isolated 12V supply from a 9–36V source
