概览

FAN604 是一款先进的 PWM 控制器，旨在通用输入范围交流/直流反激隔离电源中实现 ≥10W/in3 的功率密度。它结合了准谐振 (QR) 控制和专属的具有受限频率变化的谷开关。QR 开关减少了开关损耗，因此提供了高能效，同时具有受限频率变化的谷开关会对频带进行界定，以克服 QR 开关内在的限制。FAN604 具有 mWSaver® 突发模式运行，且运行电流极低 (300 μA)，明显降低了待机功耗， 可满足严格的能效规定，如 Energy Star 的 5 星级和 CoC 第 II 层规范。FAN604 包含一些用户可配置的功能，旨在优化能效、EMI 和保护。 FAN604 具有较宽的间隔频率范围，能够提高轻型负载能效，消除了自适应应用的噪声。 它结合了用户可配置的 恒定电流 参比， 允许从初级侧控制最大输出电流， 因此优化了变压器设计， 提高了总体能效 。它还包括了几个丰富的编程保护功能，如过电压保护 (OVP)、精确恒定输出电流调节 (CC)。

  • This product is general usage and suitable for many different applications.
  • Higher Average Efficiency by Quasi-Resonant Switching Operation with Wide Blanking Time Range
  • mWSaver® Technology for Ultra Low Standby Power Consumption (<20mW)
  • 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)
  • Programmable Over-Temperature-Protection through External NTC Resistor
  • Fully Programmable Brown-In and Brownout Protection
  • Built-In High-Voltage Startup to Reduce External Components
