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.

MARKING

DIAGRAMS

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.
