The MAX20412 is a dual-output, high-efficiency, synchronous step-down controller IC that operates with a 3.0V to 5.5V input voltage range and provides a 0.25V to 1.275V output voltage range. The controller architecture enables up to 30A of load current per phase. Channel 1 has an option to operate with two phases to deliver higher load current, making this device ideal for automotive point-of-load (PoL) and post-regulation applications.The IC achieves ±2% output error over load, line, and temperature ranges. The IC features a 2.2MHz/1.1MHz fixed-frequency PWM mode for better noise immunity and load-transient response, and a pulse-frequency modulation mode (skip) for increased efficiency during light-load operation. The 2.2MHz frequency operation allows the use of all-ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. The MAX20412 is offered with factory-preset output voltages (see the Selector Guide for options). The I2C interface supports dynamic voltage adjustment with programmable slew rates for each channel. Other features include programmable soft-start, overcurrent, and overtemperature protections.
