MAX8552ETB-MAX8552EUB
High-Speed, Wide-Input, Single-Phase MOSFET Driver
General DescriptionThe MAX8552 highly integrated monolithic MOSFET dri-
ver is capable of driving a pair of power MOSFETs in
single or multiphase synchronous buck-converter appli-
cations that provide up to 30A output current per
phase. The MAX8552 simplifies PC board layout in mul-
tiphase systems, particularly three phases and higher.
High input voltages up to 24V allow the MAX8552 to be
used in desktop, notebook, and server applications.
Each MOSFET driver is capable of driving 3000pF
capacitive loads with only 12ns propagation delay and
11ns (typ) rise and fall times, making the MAX8552
ideal for high-frequency applications.
User-programmable break-before-make circuitry pre-
vents shoot-through currents, maximizing converter effi-
ciency. An enable input allows total driver shutdown
(<1µA typ) for power-sensitive portable applications.
The PWM control input is compatible with TTL and
CMOS logic levels. The MAX8552, along with the
MAX8524 or the MAX8525 multiphase controllers, pro-
vides flexible 2-, 3-, 4-, 6-, or 8-phase CPU core-voltage
supplies.
The MAX8552 is available in space-saving 10-pin TDFN
and µMAX packages and is specified for -40°C to
+85°C operation.
