Analog Devices MAX20411

The MAX20411 is a family of 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 the ability to provide up to 40A peak output current make this device family ideal for on-board point-of-load and post-regulation applications. The MAX20411 achieves as low as ±0.75% output error over load, line, and temperature ranges.

GENERAL DESCRIPTION

The MAX20411 features a 2.1MHz fixed-frequency PWM mode for better noise immunity and load-transient response. The 2.1MHz 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. This device features the MAXQ® power architecture, which provides precision transient performance and phase margin. This allows obtaining the maximum power, performance, and precision while minimizing system cost for any specific application. The MAX20411 is offered with a factory-preset output voltage. (See the Ordering Information table for options.) The I2C interface supports dynamic voltage adjustment with programmable slew rates. Other features include programmable soft-start and overtemperature protections. Benefits and
