MAX20474EVKIT#

MAX20474EVKIT# is a MAX20474 evaluation kit (EV kit) which evaluates the performance of MAX20474 synchronous boost converter. The MAX20474 EV kit allows for typical evaluation of device performance with a fixed output or an adjustable output voltage. The MAX20474 is a high-efficiency DC-DC converter which boosts a 3 to 5.5V input supply from 6 to 18V at up to 1A load. The boost converter achieves ±1.5% output error over load, line and temperature range. The device features 2.2MHz fixed-frequency PWM mode for better noise immunity and load transient response and a pulse-frequency modulation mode (SKIP) for increased efficiency during light load operation. The 2.2MHz frequency operation allows for the use of all ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low RDSON switches improve efficiency at heavy loads and simplifies the layout with respect to discrete solutions.
