MAX20012B

Automotive Low-Voltage 2-Channel Step-Down Controller

Dual-Output, High-Efficiency Step-Down Controller for Automotive SOC Core Power


点击查看特定型号的库存状况。

说明

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 one 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.
