Microchip MCP14628 | Demoboard Battery Charger Using an Inverse SEPIC Topology

Description

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 controllers that lack integrated gate drivers. Additionally,greater design flexibility is offered by allowing the gate drivers to be placed close to the power MOSFETs.
