Product Details

The MAX20011C EV kit is a fully assembled and tested PCB intended to demonstrate the capability of the MAX20011C step-down (buck) voltage regulator. The MAX20011C has an output current rating of 16A. 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 MAX20011C features a 2.2MHz fixed-frequency pulse-width-modulation (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 spreadspectrum frequency modulation option minimizes electromagnetic emissions. Integrated low RDS(ON) switches improve efficiency at heavy loads and simplifies layout.

The MAX20011C is offered with factory-preset output voltage. The I2C interface supports dynamic voltage adjustment with programmable slew rates. Other features include programmable soft-start, over-current protection, and over-temperature protection.

The MAX20011D can be evaluated by replacing the installed IC (U1).
