TL2843BDR

Texas Instruments · AC-DC Controllers And Regulators · SOIC-14

TL2843BDR from Texas Instruments, in a SOIC-14. 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 COMP bidirectional Error amplifier compensation pin; error amplifier output sink current is limited to 10 mA maximum.
2 NC unconnected No internal connection; do not connect.
3 VFB input Error amplifier input, with recommended input voltage of 0 V to 5.5 V (absolute maximum −0.3 V to 6.3 V).
4 NC unconnected No internal connection; do not connect.
5 ISENSE input Current sense comparator input, with recommended input voltage of 0 V to 5.5 V (absolute maximum −0.3 V to 6.3 V).
6 NC unconnected No internal connection; do not connect.
7 RT/CT bidirectional Oscillator RC timing input, with recommended voltage of 0 V to 5.5 V.
8 POWER GROUND power_in Output PWM ground terminal; recommended voltage range is −0.1 V to 1 V (applies to the 14-pin D package).
9 GND power_in Device power supply ground terminal; all voltages are referenced to this pin.
10 OUTPUT output PWM output for driving an N-channel MOSFET gate; output voltage 0 V to 30 V, average output current 200 mA maximum, ±1 A peak.
11 VC power_in Output PWM positive voltage supply; recommended voltage up to 30 V (applies to the 14-pin D package).
12 VCC power_in Device positive supply; absolute maximum 30 V for a low-impedance source, with supply current self-limited when ICC is above 30 mA.
13 NC unconnected No internal connection; do not connect.
14 REF output Oscillator voltage reference output; reference output current limited to −20 mA.
