Step-down converter IRTPS

isolatedembeddedfor telecommunications equipment

Overview
The IRTPS is an isolated, regulated DC-DC converter module that converts a 9–36V DC input to an isolated 12V DC output rated at 100W (12V, 8.3A). It is intended for embedded and industrial systems requiring a dedicated isolated 12V rail and a modular approach to higher power delivery.

Key Features

• Isolated 12V output, 100W (12V, 8.3A)
• Wide input range: 9V to 36V DC
• High-frequency ZVS switching topology
• Low inrush current
• Output over-current protection (OCP) and over-voltage protection (OVP)
• Optional ignition control for vehicle/transportation power sequencing

Certifications

• CE
• FCC

Product Details
The module is designed for modular DC-DC system architectures: using multiple modules in parallel or distribution can increase power density and reduce overall footprint compared with single-part ultra-wide-input converters. The isolated output reduces conducted noise and transient coupling to sensitive downstream electronics.

Protection and Reliability
The IRTPS includes protections such as OCP, OVP, short-circuit protection and thermal shutdown. Low inrush current reduces startup stress on upstream supplies. The module is suitable for industrial and transportation environments where isolation and staged power-up are required.
