电流模式 PWM 控制器

The UCx84xA family of control devices is a pin-for-pin compatible improved version of the UCx84x family. Providing the necessary features to control current-mode or switched-mode power supplies, this family of devices has many improved features: startup current is less than 0.5 mA, oscillator discha • Optimized for Off-Line and DC-DC Converters\n• Low Start-Up Current (WEBENCH® Power Designer;
