Features and Applications

The MCP19035-AAAAE/MF is a optimized, highspeed synchronous buck controller. Operates from input voltage sources up to 30 V. This controller implements a voltage-mode control architecture with a fixed switching frequency of 300 kHz.

The high switching frequency facilitates uses smaller passive components, including the inductor and input/output capacitors, allowing a compact, high performance power supply solution. It implements an adaptive anti-cross conduction scheme to prevent shoot-through in the external power MOSFET.
