TDK has expanded its i7 series of isolated DC-DC power modules with new high-power 1/16-brick converters designed for compact, thermally demanding industrial and medical applications. The latest flagship model, I7A24080A033V, delivers up to 1000W from a footprint small enough for high-density power architectures.

With peak efficiencies up to 99%, wide input voltage options, configurable control logic, and strong thermal performance, the i7A series offers a flexible and scalable solution for next-generation embedded systems.

1. Compact 1/16-Brick Size With Up to 1000W Output

The new I7A24080A033V fits powerful performance into a compact 34 × 36.8 × 19.8 mm package.
Key features include:

   *  80A maximum output current

   *  3.3–18V adjustable output range

   *  18–32V input (optimized for 24V systems)

   *  High efficiency up to 98%

   *  Only 85g with enhanced thermal baseplate

This module reduces board space, minimizes thermal stress, and supports high-load digital systems such as FPGAs, CPUs, motor drives, and embedded processors.

2. Wide-Input Version: 18–60V for Global Applications

For systems requiring broader compatibility, TDK offers the i7A4W060A033V model with:

   *  18–60V input range

   *  3.3–28V output

   *  60A / 720W power rating

   *  Up to 99% peak efficiency

This wide-range version helps OEMs reduce the number of unique part numbers in the BOM, supporting multiple power rails with a single converter platform.

3. Flexible Control Logic & Adjustable Current Limit

Each i7A module is available in configurations with:

   *  Positive remote ON/OFF logic

   *  Negative remote ON/OFF logic

   *  Optional adjustable output current limit

The tunable current limit offers multiple benefits:

   *  Protects downstream components from inrush current

   *  Reduces short-circuit stress

   *  Supports parallel operation of multiple modules

   *  Useful for charging capacitive loads and power-hungry digital ICs

This makes the i7A series ideal for modular power systems where flexibility and reliability are critical.

4. Strong Thermal Performance for Demanding Environments

The new i7A modules feature:

   *  Enhanced baseplate for efficient heat spreading

   *  Doubled input/output pins for improved mechanical reliability

   *  Operating temperature: –40°C to +115°C

   *  Full power achievable above 90°C baseplate temperature

Thermal derating varies with airflow and input/output conditions, making the converters suitable for sealed enclosures, fan-cooled systems, and rugged industrial environments.

5. Additional 550W / 100A i7 Variant

TDK also offers a similarly sized i7 module delivering:

   *  9–18V input

   *  0.8–8V output

   *  550W and 100A output

   *  Up to 96% efficiency

This provides even more options for high-current point-of-load applications such as servers, networking equipment, and AI accelerators.

6. Compliance & Global Certifications

All i7A models meet major international power safety standards:

   *  IEC/UL/CSA/EN 62368-1

   *  CE and UKCA marks

   *  RoHS compliance

This ensures easy integration into commercial, industrial, and consumer product designs with minimal certification overhead.

7. Target Applications

The TDK i7A high-power DC-DC converters are ideal for:

   *  Medical devices

   *  Communication systems

   *  Industrial automation equipment

   *  Test and measurement instruments

   *  Robotics and AGVs

   *  UAVs and drones

   *  High-density embedded computing

These sectors require high reliability, high efficiency, and compact power solutions—areas where the i7A series excels.
