UC1845A-SP 电流模式 PWM 控制器

The UC1842A/3A/4A/5A family of control IC’s is a pin for pin compatible improved version of the UC1842/3/4/5 family.Providing the necessary features to control current-mode switched-mode power supplies, this device has the following improved features. Start up current is guaranteed to be less than 0.5 mA. Oscillator discharge is trimmed to 8.3 mA. During undervoltage lockout, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5 V.

The difference between members of this family are shown in Table 1
