Descriptions
Descriptions of Texas Instruments UC1844J883B provided by its distributors.
Current Mode PWM Controller 200mA 500kHz 8-Pin CDIP Tube
SWITCHING CONTROLLER; Temperature Grade: MILITARY; No. of Terminals: 8; Package Code: DIP; Package Shape: RECTANGULAR; Surface Mount: NO;
The UC1842A/3A/4A/5A family of control ICs is a pin for pin compatible improved version of the UC3842/3/4/5 family. Providing the necessary features to control current mode switched mode power supplies, this family has the following improved features. Start up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA. During under voltage lockout, the output stage can sink at least 10mA at less than 1.2V for VCC over 5V.
