.. NCP3420 MOSFET Driver with Dual Outputs for Synchronous Buck Converters The NCP3420 is a single Phase 12 V MOSFET gate driver optimized to drive the gates of both high- side and low- side power MOSFETs in a synchronous buck converter. The high- side and low- side driver is capable of driving a 3000 p F load with a 30 ns propagation delay and a 20 ns transition time. With a wide operating voltage range, high or low side MOSFET gate drive voltage can be optimized for the best efficiency. Internal adaptive nonoverlap circuitry further reduces switching losses by preventing simultaneous conduction of both MOSFETs. The floating top driver design can acmodate VBST voltages as high as 35 V, with transient voltages as high as 40 V. Both gate outputs can be driven low by applying a low logic level to the Output Disable (OD) pin. An Undervoltage Lockout function ensures that both driver outputs are low when the supply voltage is low, and a Thermal Shutdown function provides the IC with overtemperature protection.
