Description
The STEVAL-ISA161V1 is an evaluation board to
test the performance of the SEA01 constant
voltage and current controller with online digital
trimming from STMicroelectronics. The board
implements a 65 W adapter, targeting
applications such as power supplies for high-end
portable computers. The board uses the SEA01
as secondary side CV/CC controller, allowing the
application to satisfy very precise output voltage
and current regulations thanks to the digital
trimming technique employed. The primary side
PWM controller is the L6566B. This device drives
a TM flyback topology, the best fit for this type of
application.
The SEA01 is mounted on a small daughterboard
that includes a connector to communicate, via I²C
protocol, with an external trimming tool. This
evaluation board can therefore be useful also as
a means to test the benefits of digital trimming in
a real application. The SEA01, housed in an SO8
package, is a CV/CC controller which includes 2
transconductance op-amps and 2 voltage
references, digitally trimmable using an I²C
interface. ST also offers an advanced trimming
board (STEVAL-PCC019V1) that allows users to
perform all the trimming operations (including
automatic trimming) using a standard Windows^®-
based PC.
