Description
The regulators can either step down directly from the battery voltage to create the core voltage, or step down from the main system supply. The single-stage conversion method allows the highest possible efficiency, while the 2-stage conversion at higher switching frequency provides the minimum possible physical size.
The low-side drivers are optimized to drive 3nF capacitive loads with 4ns/8ns typical fall/rise times, and the high-side driver with 8ns/10ns typical fall/rise times. Adaptive dead-time control prevents shoot-through currents and maximizes converter efficiency.
The MAX8791/MAX8791B are available in a small, lead-free, 8-pin, 3mm x 3mm TQFN package.
