Analog Devices / Maxim Integrated MAX20011x Step-Down Converters

Analog Devices MAX20011C, MAX20011D, and MAX20011G High-Efficiency Step-Down Converters operate with a 3.0V to 5.5V input voltage range and supply 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 onboard point-of-load and post-regulation applications. The MAX20011C, MAX20011D, and MAX20011G achieve ±1.5% output error over load, line, and temperature ranges.

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 R_DS(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.
