MCP19035

The MCP19035 is 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 both a 300 kHz or 600khz switching-frequency option, 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.

Features
  • High-Speed Voltage Mode, Analog Pulse-Width Modulation Control
  • Integrated Synchronous MOSFET Drivers
  • Fixed Switching Frequency (fSW): 300 or 600 kHz
  • Multiple Dead-Time Options for low-FOM MOSFET Compatibility
  • Integrated Current Sense Capability for Short Circuit Protection
  • Integrated Linear Voltage Regulator
