The MCP19035 is an application-optimized, highspeed synchronous buck controller that operates from input voltage sources up to 30V. This controller implements a voltage-mode control architecture with afixed switching frequency of 300 kHz. The highswitching frequency facilitates the use of smaller passive components, including the inductor and input/output capacitors, allowing a compact, highperformancepower supply solution. The MCP19035 implements an adaptive anti-cross conduction scheme to prevent shoot-through in the external powerMOSFETs. Further more, the MCP19035 offers multiple dead-time options, enabling an additional degree of optimization, allowing a higher efficiencypower supply design.
The MCP19035 controller is intended to be used for applications providing up to 20A of output currents across a wide input voltage range, up to 30V.
The SHDN input is used to turn the device on and off. While turned off, the current consumption is minimized.
The MCP19035 offers a Power Good feature (PWRGD), enabling fault detection and simplifying sequencing.
