ED8106 Datasheet, PDF (1/14 Pages) Altera Corporation – Single-Rail PWM controller

Description
The ED8106 is true-digital single-phase PWM
controllers optimally configured for use with the
Altera ET4040 40A Power Train.
The ED8106 integrates a digital control loop that is
optimized for maximum flexibility and stability as
well as load step and steady-state performance. In
addition, a rich set of protection functions is
provided.
To simplify the system design, a set of optimized
configuration options have been pre-programmed
in the devices. These configurations can be
selected by setting the values of two external
resistors.
Reference solutions are available complete with
layout recommendations, example circuit board
layouts, complete bill of materials and more.
