The MAX16930ATLR/V+ is a high-voltage, synchronous step-down controller with an integrated step-up preboost controller, designed for automotive power applications. It operates with an input voltage supply from 2V to 42V, making it suitable for conditions like cold-crank or engine stop-start.
This device features two step-down controllers operating 180° out-of-phase at frequencies up to 2.2MHz, allowing for small external components and reduced output ripple. The switching frequency is resistor-adjustable, and it offers three frequency modes: forced fixed-frequency, skip mode with ultra-low quiescent current (20µA), and synchronization to an external clock. A spread-spectrum option is available to minimize EMI interference.
The integrated preboost circuitry activates during low input voltage conditions, providing power to the step-down channels down to 2V. The MAX16930ATLR/V+ includes protection features such as power-OK monitor, overvoltage and undervoltage lockout, cycle-by-cycle current limit, and thermal shutdown, enhancing system reliability.
Available in a 40-pin TQFN-EP and side-wettable QFND-EP packages, it is specified for operation over the -40°C to +125°C automotive temperature range. Its design meets stringent OEM module power consumption and performance specifications, enabling crank-ready designs and reducing interference with sensitive radio bands.
