Shenzhen Meiyuxin Technology Co., Ltd. [MAXIM Distributor] sells the new MAX20012BATJH/VY+T automotive switch controller Two-output buck controller for automotive SoC cores! ! !

General Description

The MAX20012B 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 0.5V to 1.5875V output voltage range. The controller architecture enables up to 12A 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 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 MAX20012B 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.
