Description
The MAX17409 is intended for two different notebook processor core applications: either bucking down the battery directly to create the core voltage, or bucking down the +5V system supply. The single-stage conversion method allows this device to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, 2-stage conversion (stepping down the +5V system supply instead of the battery) at higher switching frequency provides the minimum possible physical size.
A slew-rate controller allows controlled transitions between VID codes. A thermistor-based temperature sensor provides programmable thermal protection. The MAX17409 is available in a 28-pin, 4mm x 4mm TQFN package.
