TL2843BDRG4-8

Texas Instruments · AC-DC Controllers And Regulators · SOIC-8

TL2843BDRG4-8 from Texas Instruments, in a SOIC-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 COMP bidirectional Error amplifier compensation pin (listed as Input or Output in the pin table); the absolute maximum error amplifier output sink current is 10 mA.
2 VFB input Error amplifier input; the VFB analog input range is -0.3 V to 6.3 V absolute maximum, with 0 V to 5.5 V recommended.
3 ISENSE input Current sense comparator input; the ISENSE analog input range is -0.3 V to 6.3 V absolute maximum, with 0 V to 5.5 V recommended.
4 RT/CT bidirectional Oscillator RC input (listed as Input or Output in the pin table); recommended input voltage range is 0 V to 5.5 V.
5 GND power_in Device power supply ground terminal to which all device voltages are referenced.
6 OUTPUT output PWM output driving the N-channel MOSFET from a high-current totem-pole stage; recommended average output current is 200 mA and recommended output voltage is 0 V to 30 V.
7 VCC power_in Device positive supply voltage; the absolute maximum supply voltage is 30 V for a low impedance source.
8 VREF power_in Oscillator voltage reference output, with reference output current recommended at -20 mA or less.
