    The MAX20499C/MAX20499D is a high-efficiency, synchronous step-down converter that operates with a 3.0V to 5.5V input voltage range and supplies a 0.5V to 1.275V output voltage range. The wide input/output voltage range and the ability to provide up to 16A peak output current make this device ideal for on-board point-of-load and post-regulation applications. The MAX20499C/MAX20499D achieves ±1.5% output error over load, line, and temperature ranges.

    The MAX20499C/MAX20499D 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 spread-spectrum frequency modulation option minimizes radiated electromagnetic emissions. Integrated low RDS(ON) switches improve efficiency at heavy loads and make layout simpler than discrete solutions.

    The MAX20499C/MAX20499D is offered with factory-preset output voltage. The I2C interface supports dynamic voltage adjustment with programmable slew rates. Other features include programmable soft start, overcurrent, and overtemperature protections.

    Product Detail

    The MAX20499C EV kit is a fully assembled and tested PCB intended to demonstrate the capability of the MAX20499C step-down (buck) voltage regulator. The MAX20499C 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 MAX20499C 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 MAX20499C 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 MAX20499D can be evaluated by replacing the installed IC (U1).
