Advanced Synchronous Rectified Buck MOSFET Drivers with Pre-POR OVP
DATASHEET
FN9205 Rev.4.00 May 1, 2012
The ISL6612B and ISL6613B are high frequency MOSFET drivers specifically designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified buck converter topology. These drivers combined with HIP63xx or ISL65xx Multi-Phase Buck PWM controllers and N-Channel MOSFETs form complete core-voltage
regulator solutions for advanced microprocessors.
The ISL6612B drives the upper gate to above rising VCC POR (7V), while the lower gate can be independently driven over a range from 5V to 12V. The ISL6613B drives both upper and lower gates over a range of 5V to 12V. This drivevoltage provides the flexibility necessary to optimize applications involving trade-offs between gate charge and conduction losses. These drivers are optimized for POL DC/DC Converters for IBA Systems....
