ADP3422 - IMVP-II-Compliant Core Power Controller for Mobile CPUs

Description

The ADP3422 is a hysteretic dc-dc buck converter controller to power a mobile processor’s core.

The optimized low voltage design is powered from the 3.3 V system supply.

The output voltage is set by a 5-bit VID code.

Features

  • Certified IMVP-II Controller Excellent Transient Containment Minimum Number of Output Capacitors Fast, Smooth, Output Transition During VID Code Change Current Limit with Hiccup Protection Transient-Glitch-Free Power Good Low Shutdown Current Soft Start Eliminates In-Rush Current Surge Adaptive Noise-Blanking Enhancement for Speed and Stability Highly Redundant Over-Voltage and Reverse-Voltage Protection Controls Synchronous Rectifier for Improved Battery Life.
