UCC28C43MDREP

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

UCC28C43MDREP 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 output Error amplifier output for compensation with output voltage 0.1 V to 6.8 V, sink current 2 to 14 mA, source current -0.5 to -1 mA.
2 FB input Inverting input to error amplifier internally referenced at 2.5 V ± 1% with input bias current -0.1 to -2 µA.
3 CS input Noninverting input to PWM comparator with maximum input signal 0.9 V to 1.1 V and input bias current -0.1 to -2 µA.
4 RT/CT passive External timing resistor and capacitor node for programming oscillator frequency.
5 GND power_in Ground return pin for output driver stage and logic-level controller section.
6 OUT output PWM output driver with ±1 A peak output current, 20 to 40 ns fall time, 25 to 50 ns rise time, capable of directly driving MOSFET gates.
7 VDD power_in Power supply input with recommended 7 V to 18 V operating range and 20 V absolute maximum.
8 VREF power_out 5 V reference output with ±1% initial accuracy, 4.9 V to 5.1 V output voltage at 1 mA.
