Product overview
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.
