Product Details
The MAX20011 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 12A peak output current make this device family ideal for on-board point-of-load and post-regulation applications. The MAX20011 achieves ±1.5% output error over load, line, and temperature ranges.
The MAX20011 features 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 MAX20011 is offered with 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, overcurrent, and overtemperature protections.
