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

TL2842DR-8 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 COMP bidirectional Error amplifier compensation pin for feedback network impedance; can source or sink up to 0.5 mA.
2 VFB input Error amplifier input terminal with nominal 2.5 V setpoint and input voltage range 0 to 5.5 V.
3 ISENSE input Current sense comparator input with 1 V threshold and 3 V/V gain, input voltage range 0 to 5.5 V.
4 RT/CT bidirectional Oscillator RC timing input for external frequency-setting resistor and capacitor, voltage range 0 to 5.5 V.
5 GND power_in Device power supply ground terminal and reference potential for all internal circuits.
6 OUTPUT output PWM output terminal driving N-channel MOSFETs with 0 to 30 V range, sourcing/sinking up to 1 A.
7 VCC power_in Device positive voltage supply terminal with recommended operating range 30 V maximum.
8 REF output Oscillator voltage reference output providing 5 V typical with short-circuit current -30 to -180 mA.
