UC2902N

Texas Instruments · Power Management - Specialized · PDIP-8

UC2902N from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Local power supply return and signal ground; all voltages are referenced to GND.
2 SENSE input Inverting input of the current sense amplifier, rated -5 V to 5 V absolute input voltage range.
3 ADJ output Current output of the adjust amplifier circuit (NPN collector), absolute output current -1 mA to 30 mA.
4 ADJR output Adjust amplifier range set (NPN emitter), absolute input voltage -0.3 V to 4 V; a resistor to GND sets the adjust current (about 360 Ω gives about 5 mA in the typical application).
5 COMP bidirectional Output of the error amplifier and input of the adjust amplifier, absolute input voltage -0.3 V to 4 V.
6 SHARE− input Reference for the SHARE+ pin and the system ground connection of the share bus, absolute voltage -0.3 V to 10 V.
7 SHARE+ bidirectional Positive input from the share bus or drive-to-share bus, absolute voltage -0.3 V to 10 V and output current -100 mA to 10 mA.
8 VCC power_in Local power supply (positive), operating range 2.7 V to 20 V with absolute maximum -0.3 V to 20 V.
