2A Synchronous Buck Power MOSFET Driver

The MCP14628 is a dual MOSFET Gate driver designed to optimally drive two N-Channel MOSFETs arranged in a non-isolated synchronous buck converter topology. With the capability to source 2A peaks typically from both the high-side and low-side drives, the MCP14628 is an ideal companion to buck control- lers that lack integrated Gate drivers. Additionally, greater design flexibility is offered by allowing the Gate drivers to be placed close to the Power MOSFETs The MCP14628 features the capability to sink 3.5A peak typically for the low-side Gate drive. This allows the MCP14628 the capability of holding off the low-side Power MOSFET during the rising edge of the PHASE node. Internal adaptive cross conduction protection circuitry is also used to mitigate both external power MOSFETs from simultaneously conducting. The low resistance pull-up and pull-down drives allow the MCP14628 to quickly transition a 3300 pF load in typically 10 ns and with a propagation time of typically 20 ns. Bootstrapping for the high-side drive is internally implemented which allows for a reduced system cost and design complexity. The PWM input to the MCP14628 CAN be tri-stated to force both drive outputs low for true power stage shutdown. Light load system efficiency is improved by using the Diode emulation feature of the MCP14628. When the FCCM pin is grounded, Diode emulation mode is entered. In this mode, discontinuous conduc- tion is allowed by sensing when the inductor current reach zero and turning off the low-side power MOSFET By Microchip Technology Inc.
