... 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. ...
