Description
AI
The FAN6080HMX is an advanced PWM controller aimed at achieving power density of ≥10 W/in3 in universal input range AC/DC flyback isolated power supplies. It incorporates Quasi−Resonant (QR) control with proprietary valley switching. QR switching provides high efficiency by reducing switching losses.FAN6080HMX features MWSAVER® burst mode operation with extremely low operating current (300 A) and significantly reduces standby power consumption to meet the most stringent efficiency regulations such as Energy Star’s 5−Star Level and CoC Tier II specifications.FAN6080HMX includes several features aimed at optimizing efficiency, EMI and protections. FAN6080HMX has a wide blanking frequency range that improves light load efficiency. The maximum operating frequency is optimized to minimize components temperature while maximizing the full load efficiency. The minimum peak current is also set to optimize to balance the standby power consumption and the audio noise. It also includes several rich programmable protection features such as over−voltage protection(OVP) and precise constant output current regulation (CC).FAN6080HMX is available in SOIC8 package.
