The FAN5240MTCX is a single-output, 2-phase synchronous buck controller from On Semiconductor, specifically designed to power AMD's mobile CPU cores, including Athlon and Duron processors. It features a dynamic voltage setting capability using a 5-bit DAC, allowing the core PWM output voltage to be adjusted from 0.925VDC to 2.0VDC during operation. This controller supports AMD's PowerNow! technology with controlled output slew rate transitions.
Key electrical specifications include an input voltage range of 6V to 24V and an output voltage range of 0.925V to 2.0V. It boasts ±1% reference precision over temperature and high efficiency, exceeding 90% over a wide load range and 80% at light loads. The design incorporates Voltage Feed-Forward and Average Current Mode control for excellent dynamic response. Fault protections include over-voltage, over-current, and thermal shutdown.
The FAN5240MTCX is available in a 28-TSSOP package and is designed for surface mount applications. It operates within a temperature range of -10°C to 85°C. The controller includes features like active droop to reduce output capacitor size and differential remote voltage sense for improved regulation.
