RTKA226110DE0040BU
Evaluation Board
The RTKA226110DE0040BU is a gate drive evaluation board following the GS665XXX-EVBDB daughter board
style and uses the RAA226110 device. This evaluation board consists of two GaN Systems 650V GaN
Enhancement-mode HEMTs (E-HEMTs) and all necessary circuits including half-bridge gate drivers, isolated
power supplies, and an optional heatsink to form a functional half-bridge power stage. It allows you to evaluate
the GaN E-HEMT performance in any half-bridge-based topology, either with the universal mother board
(GS665MB-EVB) or your own system design. The RTKA226110DE0040BU evaluation board provides a -3V
turn-off voltage solution. A 0V turn-off solution is easy to implement as there is no need for a negative power
supply rail. For Enhancement mode (E-mode) GaN devices, the V
additional noise margin for demanding applications, the RTKA226110DE0040BU board supplies -3V to the
RAA226110 gate driver. Although this increases the body diode reverse conduction voltage drop compared to a
design with a 0V pull-down, it can still be preferred in high power, high-speed gate drive applications.
Read the entire user manual and specifically, the warnings and restrictions notices before handling the product.
Persons handling the product(s) must have electronics training and observe good engineering practice standards.
Features
• Serves as a reference design and evaluation tool in addition to a deployment-ready solution for easy in-system
evaluation.
• Vertical mount style with a height of 35mm that fits in the majority of 1U designs and allows evaluation of a GaN
E-HEMT in traditional through-hole type power supply board
• Current shunt position for switching characterization testing
• Universal form factor and footprint for all products

DANGER!
This evaluation board is designed for engineering evaluation in a controlled lab environment
and should be handled by qualified personnel ONLY. High voltage is exposed on the board
during the test and even brief contact during operation may result in severe injury or death.
Never leave the board operating unattended. After it is de-energized, always wait until all
capacitors are discharged before touching the board.
CAUTION:
This product contains parts that are susceptible to damage by Electrostatic Discharge (ESD).
Always follow ESD prevention procedures when handling the product.
