DIGITAL MULTI-PHASE GPU BUCK CONTROLLER The CHL8266 is a 6-phase digital synchronous buck controller for regulation of high-performance GPU platforms. The CHL8266 output VID table is fully compliant with VR11.1 specifications. The CHL8266 deploys a number of efficiency shaping features. PSI can be programmed to be up to four phases for optimum light-load efficiency, and the controller can autonomously add/drop phases from mid to high and back to mid current ranges to deliver 90+% efficiency across the entire load range. CHiL’s unique Adaptive Transient Algorithm, based on nonlinear digital PWM algorithms, minimizes output bulk capacitors. CHL8266 supports NTC temperature sense to report temperature and trigger VR HOT and OTP fault... |
