Microchip Technology, Inc. 2A Synchronous Buck Power MOSFET Driver MCP14628

Description
The MCP14628 is a synchronous MOSFET driver used for driving MOSFETs in a rectified bridge arrangement. This type of arrangement is typical of synchronous buck converter topologies.There are two separate drivers contained in the MCP14628. the low-side driver output drives a non-floating or ground reference N-Channel MOSFET. The high-side driver is designed to drive a floating N-Channel MOSFET. since the N-Channel is floating, this output needs to be able to handle the high voltages required to fully turn on the high-side MOSFET. An external bootstrap capacitor is used to provide the additional voltage. The MCP14628 is available in a surface mount 8 Lead SOIC package with a body width of 150 mils and the 8 Lead 3mmX3mm DFN package. Additional Features Adaptive Cross conduction protection High capacitive load drive Capability: 3000 pF in 8.0 ns (typ) Low Supply Current: 80 uA (typ) High Peak Output Current: Source 2.0A (UGATE & LGATE) Sink 2.0A (UGATE) & 4A (LGATE) Internal Bootstrap Blocking Device Enhanced Light Load Efficiency Mode Supports Floating High-Side Drive Packaging: 8 Lead surface mount SOIC, 150 mil body 8 Lead 3mmX3mm DFN
