PX3515 - Primarion

PX3515 Sychronous Rectified Buck MOSFET Driver IC

The PX3515 is a dual high speed driver designed to drive a wide range of high-side and low-side power N-channel MOSFETs.

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-free (RoHS compliant) SOIC and DFN packages Description Th.
