The MAX20010C/MAX20010D/MAX20010E ICs are high-efficiency, synchronous step-down converters that operate with a 3.0V to 5.5V input voltage range and provide a 0.5V to 1.5875V output voltage range. The wide input/output voltage range and the ability to provide up to 6A load current make these ICs ideal for on-board point-of-load and post-regulation applications. The ICs achieve ±2% output error over load, line, and temperature ranges. The MAX20010D/MAX20010E offers improved transient response.The ICs feature a 2.2MHz 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 the solution footprint. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low RDS(ON)switches improve efficiency at heavy loads and make the layout a much simpler task with respect to discrete solutions.The ICs are offered with factory-preset output voltages (see theOrdering Informationfor options). The I2C interface supports dynamic voltage adjustment with programmable slew rates. Other features include programmable soft-start, overcurrent, and overtemperature protections.

MAX20019/MAX20020 are 2.2MHz and 3.2MHz dual step-down converters with integrated high-side and low-side MOSFETs. The high-voltage step-down converter is designed for continuous operation up to 17V input voltages. The output voltage is factory preset. Buck 1 is preset to 3.3V, 3.0V, or 2.8V. Buck 2 is preset to 1.8V, 1.5V, 1.2V, or 1V. Another option is Buck 1 preset to 5V and Buck 2 preset to 3.3V.The low-voltage buck features fixed-frequency PWM- mode operation with a switching frequency of 2.2MHz or 3.2MHz. High-frequency operation allows for an all-ceramic capacitor design and small-size external components.
