Product Details

The MAX20011B EV kit is a fully assembled and tested PCB intended to demonstrate the capability of the MAX20011B step-down (buck) voltage regulator. MAX20011B has output current rating of 12A. The IC operates at 3V to 5.5V input supply voltage and can regulate to a voltage range of 0.5V to 1.275V.

The device features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response. 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 RDS(ON) switches improve efficiency at heavy loads and make the layout a much simpler task with respect to discrete solutions.

The I2C interface supports dynamic voltage adjustment with programmable slew rates. Other features include programmable soft-start, overcurrent, and overtemperature protections.

The EV kit comes pre-tested for immediate evaluation.
