NCP3488
MOSFET Driver with Dual
Outputs for Synchronous
Buck Converters
The NCP3488 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 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.
