DESCRIPTION

The TPS51601A is a synchronous buck MOSFET

driver with integrated boost switch. This high-

performance driver is capable of driving high-side and

low-side side N-channel FETs with the highest speed

and lowest switching loss. Adaptive dead-time control

and shoot-through protection are included.

The TPS51601A is available in the space-saving 8-

pin 3 mm × 3 mm SON package and operates

between –40°C and 105°C.
