Microchip MCP19035 High-Speed Synchronous Buck Controllers

Microchip MCP19035 High-Speed
Synchronous Buck Controllers

Microchip's MCP19035 High-Speed Synchronous Buck Controllers are a small, analog-based PWM controller family with integrated synchronous MOSFET drivers offering outstanding transient performance. The MCP19035 operates over a wide 4.5 - 30Vdc range, has a 300 kHz switching-frequency, and offers a factory-adjustable dead-time setting, allowing designers to optimize the performance across a wide selection of MOSFET devices. The MCP19035 family, when combined with Microchip’s MCP87xxx MOSFETs, or any low-FOM MOSFET, produces high-efficiency (>96%) DC/DC power-conversion solutions.
