UC2844A

具有 16V/10V UVLO 50% 占空比、溫度范圍為 40°C 至 85°C 的 30V、1A、500KHz 電流模式 PWM 控制器; ? Optimized for Off-Line and DC-DC Converters\n? Low Start-Up Current (WEBENCH? Power Designer;

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 discharge is trimmed to 8.3 mA, and during UVLO, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5?V.
