High-density converters

News Editor

Traco Power has announced its new TMR 12WI series of 12W DC/DC converters featuring the highest power density of 4.73W/cm³ in a standard SIP-8 package (12W in a 0.87in x 0.32in footprint).

The TMR 12WI consists of 24 models offering 4:1 input ranges of 4.5~18/9~36/18~75 VDC and output voltages of 3.3/5/12/15/24/±5/±12/±15 V outputs. Key features include 12W DC/DC in SIP-8 metal casing and power density of 4.73W/cm³. They have an ultra-wide 4:1 input & efficiency up to 90% and feature full load operation -40°C to 65°C convection. They span an operating range of -40°C to 85°C. They also feature remote on/off and indefinite short circuit protection.

These isolated DC/DC converters provide high efficiency operation up to 90% and provide an extended, full-load operation over an ambient temperature range of -40°C to 65°C without derating under natural convection conditions. Additional features include: 1,600VDC isolation; remote on/off control; continuous short circuit protection; and reliability calculated to be 960,000 hours per MIL-HDBK-217F ground benign. All models are safety approved to IEC / EN / UL 62368-1. The high density of these converters makes them an ideal solution for space critical applications in communication equipment, instrumentation and industrial electronics.
