The MAX20098ATEC/VY+ is a versatile automotive synchronous step-down buck controller designed for applications requiring mid- to high-power requirements and a wide input voltage range, such as during automotive cold-crank or engine stop-start conditions. It operates with an input supply from 3.5V to 42V and can achieve 99% duty cycle in dropout conditions.
This controller operates at a switching frequency up to 2.2MHz, allowing for smaller external components and reduced output ripple. The frequency is resistor-adjustable from 220kHz to 2.2MHz, and can be programmed via the FSYNC input for forced fixed-frequency, skip mode with ultra-low quiescent current (3.5µA in skip mode at 3.3V output), or synchronization to an external clock. It also features a factory-programmable spread-spectrum option for EMI reduction.
Key features include a wide input supply range (3.5V to 42V), adjustable output voltage from 1V to 10V, and ±1.1% output voltage accuracy for fixed 5V settings. Protection features include cycle-by-cycle current limit, thermal shutdown, supply undervoltage lockout, output overvoltage and undervoltage monitoring.
The MAX20098ATEC/VY+ is specified for operation over the -40°C to +125°C automotive temperature range and is AEC-Q100 qualified. It is available in a 16-pin TQFN (3x3) side-wettable package, suitable for surface mounting.
