Dual Advanced Synchronous Rectified Buck MOSFET Drivers with Pre-POR OVP
The ISL6614B integrates two ISL6613B MOSFET drivers and is specifically designed to drive two Channel MOSFETs in a synchronous rectified buck converter topology. This driver combined with HIP63xx or ISL65xx Multi-Phase Buck PWM controllers and N-Channel MOSFETs forms complete core-voltage regulator solutions for advanced microprocessors. The ISL6614B features 7V rising threshold and drives both the upper and lower gates simultaneously over a range from 5V to 12V. This drive-voltage provides the flexibility necessary to optimize applications involving trade-offs between gate charge and conduction losses. This driver is optimized for POL DC/DC Converters for IBA Systems. 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. These products add 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 during start-up. The ISL6614B also features a three-state PWM input which, working together with Intersil’s multi-phase PWM controllers, prevents a negative transient on the output voltage when the output is shut down. This feature eliminates the Schottky diode that is used in some systems for protecting the load from reversed output voltage events.
