MAX17019 EVALUATION KIT AVAILABLE High-Input-Voltage Quad-Output Controller General Description The MAX17019 is a high-input-voltage quad-output controller (up to 38V). The MAX17019 provides a compact, low-cost controller capable of providing four independent regulators—a main stage, a 3AP-P internal stepdown, a 5AP-P internal step-down, and a 2A source/sink linear regulator. The input voltage is up to 38V. The internal switching regulators include 5V synchronous MOSFETs that can be powered directly from a single Li+ cell or from the main 3.3V/5V power stages. Finally, the linear regulator is capable of sourcing and sinking 2A to support DDR termination requirements or to generate a fixed output voltage.
