ADP3120A  
Dual Bootstrapped, 12 V  
MOSFET Driver with Output  
Disable  
The ADP3120A is a single Phase 12 V MOSFET gate drivers  
optimized to drive the gates of both highside and lowside power  
MOSFETs in a synchronous buck converter. The highside and  
lowside driver is capable of driving a 3000 pF load with a 45 ns  
propagation delay and a 25 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 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.
