Dual mosfet driver with bootstrapping

Dual MOSFET Driver with Bootstrapping FUNCTIONAL BLOCK DIAGRAM VCC BST DRVH SW DRVL PGND IN DLY OVERLAP PROTECTION CIRCUIT ADP FEATURES All-In-One Synchronous Buck Driver Bootstrapped High Side Drive One PWM Signal Generates Both Drives Programmable Transition Delay Anticross-Conduction Protection Circuitry . The ADP is a dual MOSFET driver optimized for driving two N-channel FETs that are the two switches in the nonisolated synchronous buck power converter topology. Each driver size is optimized for performance in notebook PC regulators for CPUs in the 20 A range. The high-side driver can be bootstrapped atop.  · You must drive the MOSFET between its gate and source terminals. Since the source terminal voltage of a high side MOSFET will be floating, you need a separate voltage supply (VBS: \$V_\text{Boot Strap}\$) for the gate drive circuit. In the schematic below, VCC is the voltage source of the rest of the circuit.

The highOne PWM Signal Generates Both Drives Anti-cross Conduction Protection Circuitry. Dual Bootstrapped, 12 V MOSFET Driver with Output Disable The ADPA 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 pF load with a 25 ns.

Note 2: Notice that there are two different type of grounds. Those grounds must not be directly connected to each other. You must drive the MOSFET between its. The ADP is a dual MOSFET driver optimized for driving two N-channel switching MOSFETs in nonisolated synchro- nous buck power converters used to power. operate on the bootstrap principle or with a floating power supply. Used in the bootstrap mode, Those MGDs with two gate drive channel can have dual.
