The MAX20098ATEG/VY+ is a versatile automotive synchronous step-down controller designed for applications requiring a wide input voltage range, such as during cold-crank or engine stop-start conditions. It operates from a 3.5V to 42V supply and can achieve a 99% typical duty cycle in dropout conditions.
This controller IC features a switchable frequency up to 2.2MHz, allowing for smaller external components and reduced output ripple. It offers multiple operating modes, including forced fixed-frequency, skip mode for ultra-low quiescent current (3.5µA in skip mode at 3.3V output), and synchronization to an external clock. The device includes a factory-programmable spread-spectrum option to minimize EMI interference.
Protection features include cycle-by-cycle current limit, thermal shutdown, supply undervoltage lockout, and output over/undervoltage monitoring, enhancing system reliability. The MAX20098 is specified for operation over the -40°C to +125°C automotive temperature range and is available in a 16-pin TQFN-EP package.
Key applications include infotainment systems, USB hubs, and general-purpose point-of-load power supplies.
