Half-bridge buck converter evaluation board
using the EiceDRIVER™ 2EDL8x2x
Order code: EVAL_HB_2EDL8x2x
About this document
Scope and purpose
The 2EDL8x2x is the EiceDRIVER
voltage. 2EDL802x takes in independent inputs while the 2EDL812x takes in differential inputs. Both have a 3 A
or 4 A peak source current capability for both high-side and low-side, and a strong 5 A high-side and 6 A low-
side sink current capability.
The half-bridge buck converter evaluation board described in this document is designed as a test platform for
evaluating the performance of 2EDL8024G.
Intended audience
Power supply designers, component engineers, hardware engineers, etc.
