... ISL6595 Digital Multi-Phase Buck PWM controller and N-Channel MOSFETs form a complete core-voltage regulator solution for advanced microprocessors. The PX3511A drives the upper gate to 12V, while the lower gate can be independently driven over a range from 5V to 12V. The PX3511B drives both upper and lower gates over a range 12V ...

... Connect this pin to a +12V bias supply. Place a high quality low ESR ceramic capacitor from this pin to GND PVCC This pin supplies power to both upper and lower gate drives in PX3511B; only the lower gate drive in PX3511A. Its operating range is +5V to 12V. Place a high quality low ESR ceramic capacitor from this pin to GND PHASE Connect this pin to the SOURCE of the upper MOSFET and the DRAIN of the lower MOSFET ...

... FL t PDLL Operation Designed for versatility and speed, the PX3511A and PX3511B MOSFET drivers control both high-side and low- side N-Channel FETs of a half-bridge power train from one externally provided PWM signal. Prior to VCC exceeding its POR level, the Pre-POR overvoltage protection function is activated during initial startup ...

... The PX3511A and PX3511B provide the user flexibility in choosing the gate drive voltage for efficiency optimization. The PX3511A upper gate drive is fixed to VCC [+12V], but the lower drive rail can range from 12V down to 5V depending on what voltage is applied to PVCC. The PX3511B ties the upper and lower drive rails together ...
