UCC28051DR 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 | VO_SNS | input | Senses boost regulator output voltage through a voltage divider with nominal value of 2.5 V as the inverting input to the transconductance amplifier. |
| 2 | COMP | output | Transconductance error amplifier output with 10-μA typical output current capability and dynamic input range of 2.5 V to 3.8 V. |
| 3 | MULTIN | input | Senses boost regulator input voltage through a voltage divider with recommended operating range of 0 V to 2.5 V at high line. |
| 4 | CS | input | Senses instantaneous switch current in the boost switch for internal PWM comparator ramp with internal clamp terminating switching if voltage exceeds 1.7 V. |
| 5 | ZCD | input | Input for zero current detect comparator with active voltage clamps and 400-μs reset timer if zero current is not detected. |
| 6 | GND | power_in | Chip reference ground with all bypassing elements connected using shortest loops feasible. |
| 7 | DRV | output | Gate drive output for external boost switch capable of delivering up to 750-mA peak currents and held low below UVLO threshold. |
| 8 | VCC | power_in | Supply voltage for the chip requiring bypass with high-frequency capacitor greater than 0.1-μF; UCC28051 has narrow UVLO hysteresis of approximately 2.8 V. |
