LM5114BSD/NOPB Datasheet PDF - TI

●The LM5114BSD/NOPB is a single low-side Gate Driver for use with boost converters. The LM5114 is designed to drive low-side MOSFETs in boost-type configurations or to drive secondary synchronous MOSFETs in isolated topologies. With strong sink current capability, the LM5114 can drive multiple FETs in parallel. The LM5114 also has the features necessary to drive low-side enhancement mode Gallium Nitride (GaN) FETs. The LM5114 provides inverting and non-inverting inputs to satisfy requirements for inverting and non-inverting gate drive in a single device type. The inputs of the LM5114 are TTL/CMOS logic compatible and withstand input voltages up to 14V regardless of the VDD voltage. The LM5114 has split gate outputs, providing flexibility to adjust the turn-ON and turnoff strength independently. The LM5114 has fast switching speed and minimized propagation delays, facilitating high-frequency operation.
