com Dual Bootstrapped, 12 V MOSFET Driver with Output Disable ADP3110 GENERAL DESCRIPTION The ADP3110 is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, which are the two switches in a nonisolated synchronous buck power converter.
Each of the drivers is capable of driving a 3000 pF load with a 25 ns propagation delay and a 30 ns transition time.
One of the drivers can be bootstrapped and is designed to handle the high voltage slew rate associated with floating high-side gate drivers.
The ADP3110 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.
The OD pin shuts off both the high-side and the low-side MOSFETs to prevent rapid output capacitor discharge during system shutdown.
The ADP3110 is specified over the commercial temperature range of 0°C to 85°C and is available in an 8-lead SOIC_N package.
FEATURES All-in-one synchronous buck driver Bootstrapped high-side drive One PWM signal generates both drives Anticross-conduction protection circuitry Output disable control turns off both MOSFETs to float output per Intel® VRM 10 specification APPLICATIONS Multiphase desktop CPU supplies Single-supply synchronous buck converters SIMPLIFIED FUNCTIONAL BLOCK DIAGRAM 12V VCC 4 D1 ADP3110 BST 1 CBST2 CBST1 IN 2 8 DRVH RG Q1 RBST DELAY TO INDUCTOR SW 7 CMP VCC 6 CMP 1V CONTROL LOGIC DRVL 5 Q2 DELAY OD 3 PGND 05514-001 6 Figure 1.
