ADP3110A
Dual Bootstrapped, 12 V
MOSFET Driver with Output
Disable
The ADP3110A is a single Phase 12 V MOSFET gate drivers
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 30 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.
Features
• All−In−One Synchronous Buck Driver
• Bootstrapped High−Side Drive
• One PWM Signal Generates Both Drives
• Anticross Conduction Protection Circuitry
• OD for Disabling the Driver Outputs Meets CPU VR Requirement
when Used with Patented FlexModet Controller
• These are Pb−Free Devices
Applications
• Multiphase Desktop CPU Supplies
• Single−Supply Synchronous Buck Converters
