UCC28083DR

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

UCC28083DR 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 CTRL input Error voltage input to the PWM comparator, with an internal divider ratio of 0.45 and absolute limits of -0.3 V to VDD + 0.3 V.
2 ISET input Slope-compensation current select: a resistor RSET from ISET to ground sets the ramp, with RSET required to be greater than 5 kΩ.
3 CS input Current-sense input to the PWM comparator, cycle-by-cycle current limit and overcurrent comparator, with an overcurrent threshold of 0.70 to 0.80 V and absolute limits of -0.3 V to VDD + 0.3 V, not to exceed 6 V.
4 RT input Oscillator programming pin: an external resistor to GND sets the oscillator frequency, with a recommended resistor range of 25 kΩ to 698 kΩ and RT voltage limits of -0.3 V to 2.0 V.
5 GND power_in Reference and power ground for all functions; a low-impedance ground plane is highly recommended due to high currents and high-frequency operation.
6 OUTB output Alternating high-current push-pull output stage capable of 500 mA peak source and 1 A peak sink to drive a power MOSFET gate.
7 OUTA output Alternating high-current push-pull output stage capable of 500 mA peak source and 1 A peak sink to drive a power MOSFET gate.
8 VDD power_in Power input with a supply voltage rating of 15 V maximum (IDD < 10 mA) and a 20 mA maximum supply current; bypass to GND with a 1-µF decoupling capacitor.
