Introduction
The MAX20030/MAX20031 ICs are automotive 2.2MHz dual-synchronous step-down controllers with preboost controller and low-lQ LDO. The preboost controller enables VOUT1 and VOUT2 to stay in regulation during cold-crank operation all the way down to battery input of 2V. The ICs offer two high-voltage synchronous stepdown controllers that operate 180 degrees out of phase. This device operates with an input-voltage supply from 3.5V to 42V and can operate in dropout conditions by running at 97% duty cycle. It is intended for applications with mid- to high-power requirements that operate at a wide input voltage range, such as during automotive cold-crank or engine stop-start conditions. The step-down controllers operate at a frequency of up to 2.2MHz to allow small external components, reduced output ripple, and to guarantee no AM band interference. The switching frequency is resistor-adjustable (220kHz to 2200kHz). SYNC input programmability enables three frequency modes for optimized performance: forced fixedfrequency operation, skip mode with ultra-low quiescent current, and synchronization to an external clock. The ICs have a spread-spectrum pin for frequency modulation to minimize EMI interference. The ICs will be offered with a synchronous step-up controller. This preboost circuitry turns on during low input-voltage conditions, and is designed to provide power to step-down controller channels with input voltages as low at 2V. The ICs feature a power-OK monitor and overvoltage and undervoltage lockout. Protection features include cycle-by-cycle current limit and thermal shutdown. The MAX20030/MAX20031 are specified for operation over the -40°C to +125°C automotive temperature range.
