Richtek RTQ2105 | Demoboard RTQ2105GQWT-QA

Description

The RTQ2105GQWT-QA evaluation board showcases the regulator’s performance, delivering 3A output from a 3V to 36V input at 2.1MHz. Suitable for industrial and communication systems, it offers protection against shorted outputs, input under voltage, overcurrent, and thermal shutdown. The documentation includes a BOM, typical application,board overview, power-up procedure, performance summary, and hardware description to provide information on the board’s components, capabilities, and usage.
