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.
