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-free (RoHS compliant) SOIC and DFN packages
Description
The PX3515 is a dual high speed driver designed to drive a
wide range of high-side and low-side power N-channel
MOSFETs in synchronous rectified buck converters. When
combined with the Primarion PX35XX family of Digital Multi-
phase Controllers or PX75XX Digital Point of Load (Di-
POLTM) Controllers and N-channel MOSFETs, the PX3515
forms a complete core-voltage regulator solution for
advanced micro and graphics processors as well as point-
of-load applications.
The PX3515 provides the capability of driving the high-side
gate and low-side gate with independent drive voltages
over a range from 7V to 12V (high-side VCC) and 5V to
12V (low-side PVCC). This provides the flexibility necessary
to optimize applications involving trade-offs between gate
charge and conduction losses.
Adaptive zero shoot-through protection is integrated into the
IC which prevents both upper and lower MOSFETs from
conducting simultaneously and to minimize dead time. The
PX3515 has small propagation delay from input to output
with fast rise and fall times.
The PX3515 drivers also feature a three-state PWM input
which, when used together with Primarion’s Digital
Controllers, eliminates the need for Schottky diodes that are
often used in systems to protect the load from reversed
output voltage events.
