Description

The MAX8552 highly integrated monolithic MOSFET driver can drive a pair of power MOSFETs in single or multiphase synchronous buck-converter applications that provide up to 30A output current per phase. The MAX8552 simplifies PC board layout in multiphase 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 can drive 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 prevents shoot-through currents, maximizing converter efficiency. 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, provides 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.
