UCC2800DTR
Texas Instruments · AC-DC Controllers And Regulators · SOIC-8
UCC2800DTR 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 | COMP is the error amplifier output and PWM comparator input, can both source and sink current, and forcing it to GND commands zero duty cycle. |
| 2 | FB | input | FB is the inverting input of the error amplifier, and its lead length and stray capacitance should be kept as small as possible for best stability. |
| 3 | CS | input | CS is the input to the PWM and overcurrent comparators, with 100-ns leading-edge blanking after the rising edge of OUT, and exceeding the overcurrent threshold causes a soft-start cycle. |
| 4 | RC | input | RC is the oscillator timing pin, with timing resistors between 10 kΩ and 200 kΩ from REF and timing capacitors between 100 pF and 1000 pF to GND, and a timing resistor less than 10 kΩ must never be used. |
| 5 | GND | power_in | GND is the reference ground and power ground for all functions on this part. |
| 6 | OUT | output | OUT is a high-current power driver for a power MOSFET gate with peak currents exceeding ±750 mA, and it is actively held low when VCC is below the UVLO threshold. |
| 7 | VCC | power_in | VCC is the power input, which in normal operation is supplied through a current-limiting resistor and requires a minimum of 1 µF in parallel with a 0.1-µF ceramic capacitor to GND placed close to the device. |
| 8 | REF | output | REF is the voltage reference for the error amplifier and other functions, is pulled to ground through 5 kΩ when VCC is above 1 V and below UVLO, and requires a minimum of 0.1-µF ceramic bypass to GND. |
