OZ8384LN OZ8384 8384

Description:

OZ8384 is a DC/DC controller specifically developed to support power supply designs for AMD SVI (Serial Voltage Identification) mobile microprocessors. It incorporates the AMD 7-bit VID table for full range output conversion capability in 12.5mV increments. High efficiency under both light and heavy load conditions, DC accuracy, remote voltage sensing and excellent transient response make OZ8384 the solution of choice for low voltage CPU conversion. OZ8384’s core topology is based on constant-ripple-current (CRC) technology.

Features:

• Dual Phase DC/DC controller for AMD
• Integrated drivers and boost diode
• AMD SVI 7-bit VID code compliant
• CRC control method allows designing for optimum inductor size
• Highly efficient power conversion up to 94%
• Highly efficient light load conversion via smart pulse skipping mode • Ultra fast transient recovery; and 1% output voltage accuracy
• Supports up to 50A output current
• User-adjustable switching frequency and Dual OCP limit
• User-adjustable slew control of VDD_CORE at start-up and OTF VID code changes
• True differential output voltage remote sensing
• Open drain Power Good signal; VR_TTb signal; and Voltage feed-forward compensation 
• Protection includes: VIN & VDDA under-voltage lockout, latched overvoltage, and cycle-by-cycle over-current
