XP Power BCT40T Brings 40W DC-DC Conversion to a 1” x 1” Format

In industrial electronics, it is often board space rather than silicon that sets the limits. Designers may want to add new sensors, communications modules, or safety features, but the size of the power supply can dictate what is actually possible. That makes converter footprint a critical design constraint, especially in robotics, automation, and test equipment.

XP Power’s new BCT40T series addresses this by squeezing 40W into a case just 1” square. Traditional 40W converters usually measure 2” x 1”, so the board area required is cut by half. For engineers, that saving can translate into smaller enclosures, additional functionality, or simply an easier route to fitting everything onto a single board.

Features Engineers Can Use

The devices are offered with input ranges of 9–36V and 18–75V, covering both 24V and 48V supply systems. Outputs span single rails from 3.3V to 24V, with dual versions at ±12V and ±15V. A trim function on single-output models lets rails be shifted by ±10% to meet specific system needs. Rather than adding a secondary regulator, designers can adjust supply voltages directly within the converter.

Efficiency and Resilience

Efficiency levels reach up to 89%, easing thermal pressure in compact systems. The converters are rated for operation between –40°C and +105°C and maintain full load across a wide range. Built-in protection covers overloads, short-circuits, under-voltage conditions, and over-temperature events. Input-to-output isolation is specified at 2kV, and remote on/off control allows systems to cut power when not in use.

Why It Matters

By cutting the footprint of a 40W converter in half, XP Power has given engineers more freedom to balance performance and space. In environments where every square millimetre counts, the BCT40T series offers a practical way to simplify layouts and support the next generation of compact industrial and communications hardware.
