An Infineon Technologies Company
Sychronous Rectified Buck MOSFET Driver IC
Datasheet
PX3515
Applications
• Core power regulation for Intel® and AMD®
μprocessors
• High current DC-DC converters
• POL power converters for memory, DSP, FPGA, ASIC
Features
• Dual MOSFET driver for synchronous rectified bridge
converters
• Adjustable high-side and low-side MOSFET gate drive
voltages for optimal efficiency
- High-side VCC (7V to 12V) - Low-side PVCC (5V to 12V) • Integrated bootstrap diode for reduced part count • Adaptive gate drive control prevents cross-conduction • Fast rise and fall times supports switching rates of up
to 2MHz
• Capable of sinking more than 4A peak current for low
switching losses
• Three-state PWM input for output stage shutdown • VCC under-voltage protection • Lead-fre
