UCC3810DW 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 and requires a pulse at least 10 ns wide; if unused it may be grounded, left open, or connected to REF. |
| 2 | CT | output | Oscillator timing capacitor node; the timing capacitor connects directly across CT and GND, with recommended values between 100 pF and 1 nF. |
| 3 | RT | output | Oscillator timing resistor node regulated to 1 V, setting the charging current at 10 V/RT, with recommended RT values between 10 kΩ and 470 kΩ. |
| 4 | FB1 | input | High-impedance inverting input of error amplifier 1, with FB input voltage of 2.50 V typical (2.44 V to 2.56 V) and input bias current of ±1 µA. |
| 5 | COMP1 | output | Low-impedance output of error amplifier 1, which sets the PWM 1 control level. |
| 6 | CS1 | input | Current-sense input to PWM comparator 1 with leading-edge blanking that disconnects CS from internal circuits for the first 55 ns of each PWM cycle, and a small R-C filter may be needed in noisy applications. |
| 7 | OUT1 | output | High-current push-pull output of PWM 1 intended to drive power MOSFET gates through a small series resistor (10 Ω is typical for most applications). |
| 8 | GND | power_in | Ground reference for the control circuits, which must be electrically connected to PWRGND while avoiding coupling of noise into GND. |
| 9 | PWRGND | power_in | Power ground for the high-current output stages, which must be electrically connected to GND. |
| 10 | OUT2 | output | High-current push-pull output of PWM 2 intended to drive power MOSFET gates through a small series resistor that limits current and damps ringing. |
| 11 | CS2 | input | Current-sense input to PWM comparator 2 with leading-edge blanking of the first 55 ns of each PWM cycle, and a small R-C filter may be needed in noisy applications. |
| 12 | COMP2 | output | Low-impedance output of error amplifier 2, which sets the PWM 2 control level. |
| 13 | FB2 | input | High-impedance inverting input of error amplifier 2, with FB input voltage of 2.50 V typical (2.44 V to 2.56 V) and input bias current of ±1 µA. |
| 14 | ENABLE2 | input | Logic input that disables PWM 2 when low, with no effect on PWM 1; it is internally pulled high, has TTL-compatible thresholds, and may be left floating. |
| 15 | REF | output | 5-V reference output that should be bypassed to GND with a ceramic capacitor of at least 0.01 µF for best performance, with output of 4.85 V to 5.10 V over the full temperature range and up to 5 mA load. |
| 16 | VCC | power_in | Power input supplying all functions including the output stages and precision reference, to be bypassed to PWRGND with a 0.1-µF ceramic capacitor; the absolute maximum is 11 V with supply current limited to 20 mA. |
