EVAL_3823A_1.2VOUT
Überblick
IR3823A evaluation board configured for 1.2 V output
The EVAL_3823A_1.2VOUT demonstrates a typical application design of IR3823A, a fully integrated 3 A DC-DC buck regulator that uses a compensation-free fast constant-on-time (COT) control. The board enables complete configuration and showcases the key benefits of IR3823A, i.e., easy-to-use fast COT PWM engine, high efficiency, accurate output voltage regulation, superior transient response, low BOM, etc.
