Microchip Technology 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 4.5Vdc to 30Vdc range, has a 300kHz 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 MCP87 MOSFETs, or any low-FOM MOSFET, produces high-efficiency (>96%) DC/DC power conversion solutions.
