... Multi-Phase Buck PWM controller, such as ISL6223, ISL6215, and ISL6216, forms a complete single-stage core-voltage regulator solution for advanced mobile microprocessors. The ISL6207 features 4A typical sink current for the lower gate driver. The 4A typical sink current is capable of holding the lower MOSFET gate during the Phase node rising edge to prevent the shoot-through power loss caused by the high dv/dt of the Phase node ...

... MOSFET. This pin provides a return path for the upper gate driver. Description Operation Designed for speed, the ISL6207 dual MOSFET driver controls both high-side and low-side N-Channel FETs from one externally provided PWM signal. A rising edge on PWM initiates the turn-off of the lower MOSFET (see Timing Diagram) ...

... MOSFET and prevent a shoot through caused by the high dv/dt of the phase node. Three-State PWM Input A unique feature of the ISL6207 and other Intersil drivers is the addition of a shutdown window to the PWM input. If the PWM signal enters and remains within the shutdown window for a set holdoff time, the output drivers are disabled and both MOSFET gates are pulled and held low ...

... Worst-case leakage currents are on the order of pico-amps; therefore, a 10kΩ resistor, connected from UGATE to PHASE, is more than sufficient to bleed off any stray leakage current. This resistor will not affect the normal performance of the driver or reduce its efficiency. 8 ISL6207 FN9075.8 December 2, 2005 ...
