UCC2810DW from Texas Instruments, in a SOIC-16-300mil. 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 | SYNC | input | Edge-triggered TTL-threshold logic input that synchronizes the oscillator to an external free-running oscillator, requiring a pulse at least 10 ns wide; if unused it may be grounded, left open, or connected to REF. |
| 2 | CT | passive | Oscillator timing capacitor node; recommended CT is between 100 pF and 1 nF, connected directly across CT and GND. |
| 3 | RT | passive | Oscillator timing resistor node, regulated to 1 V, with recommended values between 10 kΩ and 470 kΩ; higher RT gives higher maximum duty cycle and slightly lower power consumption. |
| 4 | FB1 | input | High-impedance inverting input of error amplifier 1. |
| 5 | COMP1 | output | Low-impedance output of error amplifier 1. |
| 6 | CS1 | input | Current-sense input to PWM comparator 1 with leading-edge blanking that ignores the signal for the first 55 ns of each PWM cycle; a small R-C filter may be needed in noisy or slow-diode applications. |
| 7 | OUT1 | output | High-current push-pull output for PWM 1 intended to drive a power MOSFET gate through a small series resistor. |
| 8 | GND | power_in | Control-circuit ground that must be electrically connected to PWRGND while keeping noise out of this pin. |
| 9 | PWRGND | power_in | Power ground for the output stages that must be electrically connected to GND. |
| 10 | OUT2 | output | High-current push-pull output for PWM 2 intended to drive a power MOSFET gate through a small series resistor. |
| 11 | CS2 | input | Current-sense input to PWM comparator 2 with leading-edge blanking for the first 55 ns of each PWM cycle; a small R-C filter may be needed in noisy or slow-diode applications. |
| 12 | COMP2 | output | Low-impedance output of error amplifier 2. |
| 13 | FB2 | input | High-impedance inverting input of error amplifier 2. |
| 14 | ENABLE2 | input | TTL-compatible logic input that disables PWM 2 when low, has no effect on PWM 1, and is internally pulled high (may be left floating). |
| 15 | REF | power_out | 5-V reference output that should be bypassed to GND with a ceramic capacitor of at least 0.01 µF. |
| 16 | VCC | power_in | Power input supplying all device functions including the high-current output stages and precision reference, to be bypassed directly to PWRGND with a 0.1 µF ceramic capacitor. |
