Desktop Solutions

Today’s desktop PC challenges power designers to provide a reliable yet cost effective voltage regulator (VR) solution with increasing demands for higher efficiency and flexibility. Desktop processors require high currents at low voltage levels, up to 130A at around 1.0V, due to their increased clock frequencies and smaller process geometries. The processor core voltage must remain within the strict regulation limits, under both DC and high-slew-rate current transient conditions. Violation of these specifications may result in a blue screen or reduced operating life.

CHiL provides unique digital VR Controllers and MOSFET drivers for interleaved multiphase buck converters to meet these demanding requirements

Multiphase PWM Controllers

CHiL’s non linear multiphase controllers deliver

• Best in class transient response - orders of magnitude better than the traditional analog solutions to minimize use of costly, bulky, and unreliable output capacitors
• Highly accurate operating parameters over the life of the product across PVT (Process Voltage Temperature) variations
  • Eliminates feedback components and reduces other external passives (resistors & capacitors) required to deliver an efficient & compact VR solution
• Flexible digital architecture accessible through a Graphic User Interface (GUI) allows easy re-use and customization of design with minimum board changes
  • Easy inventory management
• Accurate phase current balancing prevents the need for oversizing components & optimal component rating
• Reliable power sequencing & comprehensive fault coverage
• Real BOM savings, reduced time to market for new designs
