These Step-Down Converters feature a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response. The 2.2MHz frequency operation allows for 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 modules are 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 protection. Analog Devices MAX20011C, MAX20011D, and MAX20011G Step-Down Converters are offered in a 3.5mm x 4.0mm, 17-pin side-wettable FC2QFN package.
