General Description

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-ofload

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 RDS(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 softstart,

overcurrent, and overtemperature protections.
