The MAX20011E/MAX20011F/MAX20011G are high-efficiency, synchronous step-down converters that 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 ability to provide up to 16A peak output current make these devices ideal for on-board point-of-load and post-regulation applications. The MAX20011E/MAX20011F/MAX20011G achieve ±1.5% output error over load, line, and temperature ranges.

The MAX20011E/MAX20011F/MAX20011G feature 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 R_DS(on) switches improve efficiency at heavy loads and make layout simpler than discrete solutions.

The MAX20011E/MAX20011F/MAX20011G 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 protections.
