MAX20010C

Automotive Single 6A Step-Down Converters

High-Accuracy, Fully Integrated and Synchronous 6A Converters with Flexible DVS

概述

说明

The MAX20010C/MAX20010D 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 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 R_DS(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 the Ordering Information for options). The I²C interface supports dynamic voltage adjustment with programmable slew rates. Other features include programmable soft-start, overcurrent, and overtemperature protections.
