Multiphase Buck Controllers
CHiL intelligent multiphase buck PWM controllers are the key component in high frequency voltage regulator (VR) designs for powering today’s high performance microprocessors (CPUs) and graphics processors (GPUs). They are fully compliant with industry standard processor vendor VR specifications.
- Non-linear digital algorithms deliver best-in-class transient performance to reduce the need for output decoupling bulk capacitors.
- Increases system reliability, reduces component count & cost and saves valuable board space.
- Patented power monitoring and efficiency shaping techniques allow application based configuration and adjust system performance in real time.
- Delivers power savings and provides a thermally superior solution even during swings in power demand by the processor from 5% to 95%.
- Advanced digital power management design eliminates the feedback components and greatly reduces the need for programming passives.
- The register based “set and forget” approach delivers unmatched flexibility and scalability in VRD/ VRM design development and configuration reducing time to market and simplifying inventory control.
- CHiL PWM controllers are supported by the Intuitive Power Designer (IPD), a comprehensive GUI which encompasses and simplifies the design, configuration and monitoring processes and easily brings a digital VR to production.
