Dual Bootstrapped 12 V
MOSFET Driver with
Output Disable
The NCP3418 and NCP3418A are dual MOSFET gate drivers
optimized to drive the gates of both highside and lowside power
MOSFETs in a synchronous buck converter. Each of the drivers is
capable of driving a 3000 pF load with a 25 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 accommodate VBST voltages as
high as 30 V, with transient voltages as high as 35 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.
The NCP3418A is identical to the NCP3418 except that there is no
internal charge pump diode.
The NCP3418 is pintopin compatible with Analog Devices
ADP3418 with the following advantages:
Faster Rise and Fall Times
Internal Charge Pump Diode Reduces Cost and Parts Count
Thermal Shutdown for System Protection
Integrated OVP
Internal Pulldown Resistor Suppresses Transient Turn On of Either
MOSFET
