Advanced Synchronous Buck MOSFET Driver With 3V PWM Interface And Advanced Protection Features

The ISL6594D is high frequency MOSFET driver specifically designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified buck converter topology. This driver combined with the ISL6594D Digital Multi-Phase Buck PWM Controller and N-Channel MOSFETs forms a complete core-voltage Regulator solution for advanced Microprocessors
The ISL6594D drives both upper and lower Gates over a range of 4.5V to 13.2V. This drive-voltage provides the flexibility necessary to optimize applications involving trade-offs between Gate charge and conduction losses.
An advanced adaptive zero shoot-through protection is integrated to prevent both the upper and lower MOSFETs from conducting simultaneously and to minimize the dead time. The ISL6594D includes an overvoltage protection feature operational before VCC exceeds its turn-on threshold, at which the PHASE node is connected to the Gate of the low side MOSFET (LGATE). The output voltage of the converter is then limited by the threshold of the low side MOSFET which provides some protection to the Microprocessor if the upper MOSFET(s) is shorted.
The ISL6594D also features an input that recognizes a high-impedance state, working together with Intersil multiphase PWM Controllers to prevent negative transients on the controlled output voltage when operation is suspended. This feature eliminates the need for the Schottky Diode that may be utilized in a power system to protect the load from negative output voltage damage.
