The FAN602 is an advanced PWM controller aimed at achieving power density of ≥10W/in³ in universal input range AC/DC flyback isolated power supplies. It incorporates Quasi-Resonant (QR) control with proprietary Valley Switching with a limited frequency variation. QR switching provides high efficiency by reducing switching losses while Valley Switching with a limited frequency variation bounds the frequency band to overcome the inherent limitation of QR switching.
FAN602 features mWSaver® burst mode operation with extremely low operating current (300 μA) andsignificantly reduces standby power consumption to meet the most stringent efficiency regulations such as Energy Star’s 5-Star Level and CoC Tier II specifications.
  • High Efficiency Across Wide Input and Output Conditions in a Small Form Factor
  • Quasi-Resonant Switching Operation with Programmable Maximum Blanking Frequency Range (60 kHz~ 140 kHz)
  • User Configurable Burst Mode Entry and Exit to Maximize Light Load Efficiency and Minimize Audible Noise
  • Adaptive Burst Mode Entry Level for Adaptive Charger Application
  • mWSaver® Technology for Ultra Low Standby Power Consumption (<20 mW)
  • Forced and Inherent Frequency Modulation of Valley Switching for Low EMI Emissions and Common Mode Noise
  • Built-In and User Configurable Over-Voltage Protection (OVP), Under-Voltage Protection (UVP) and Over-Temperature Protection (OTP)
  • Fully Programmable Brown-In and Brownout Protection
  • Precise Constant Output Current Regulation with Programmable Line Compensation
  • Built-In High-Voltage Startup to Reduce External Components
  • 10 Lead SOIC JEDEC
  • This product is general usage and suitable for many different applications.
