TL3844DR

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

TL3844DR 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, with the error amplifier output sink current limited to 10 mA.
2 NC unconnected Do not connect.
3 VFB input Error amplifier input, with a recommended input voltage range of 0 V to 5.5 V.
4 NC unconnected Do not connect.
5 ISENSE input Current sense comparator input, with a recommended input voltage range of 0 V to 5.5 V.
6 NC unconnected Do not connect.
7 RT/CT bidirectional Oscillator RC input, with a recommended input voltage range of 0 V to 5.5 V and an oscillator frequency range of 100 kHz to 500 kHz.
8 POWER GROUND power_in Output PWM ground terminal, with a recommended voltage of -0.1 V to 1 V (D package only).
9 GND power_in Device power supply ground terminal, to which all device voltages are referenced.
10 OUTPUT output PWM output, rated for 0 V to 30 V output voltage, 200 mA average output current, and ±1 A absolute maximum output current.
11 VC power_in Output PWM positive voltage supply, recommended up to 30 V (D package only).
12 VCC power_in Device positive voltage supply, recommended up to 30 V with externally limited supply current of 25 mA.
13 NC unconnected Do not connect.
