Isolated DC/DC converter IRT30

embeddedfor telecommunications equipmentvehicle

Product
The IRT30 is an isolated DC-DC converter module that converts a wide unregulated input (9–36V DC) to a regulated isolated 12V DC output rated at 30W.

Key features

• High-efficiency DC-DC converter (up to 90% at full load)
• Low inrush current for reliable startup
• Output over-current protection (OCP) and over-voltage protection (OVP)
• Wide input voltage range: 9–36V DC
• Electrical isolation between input and output

Certifications

• CE
• FCC

Overview
The IRT30 is designed for embedded, industrial and automotive environments where an isolated 12V rail and dependable startup behavior are required. Its modular DC-DC architecture supports higher power density and simplifies integration when multiple converters are deployed in a system.

Design and protection features
The converter uses a high-frequency Zero Voltage Switching (ZVS) topology to maintain consistent efficiency across the input range. Integrated protections include output over-current protection, over-voltage protection, short-circuit protection, thermal protection and low inrush characteristics to reduce stress on upstream power sources and downstream electronics.

Applications

• Automotive electronics and vehicle-mounted systems
• Industrial controllers, sensors and actuators
• Telecommunications and embedded OEM equipment requiring an isolated 12V rail
