UCC28063ADR from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ZCDB | input | Zero-current detection input for phase B with 1.0V falling threshold and 1.7V rising threshold; input clamped between 0V and 3V. |
| 2 | VSENSE | input | Output voltage sense input regulated to 6.0V reference with 1.25V enable threshold; overvoltage protection thresholds at 6.48V and 6.67V. |
| 3 | TSET | input | Timing set resistor input to ground (66.5kΩ to 400kΩ range) for programming PWM on-time factor and minimum switching period between 25kHz and 50kHz. |
| 4 | PHB | input | Phase B enable/disable control input; below 0.8V threshold disables phase B and phase-fail detection; above 1.0V threshold enables two-phase operation. |
| 5 | COMP | output | Error amplifier transconductance output for voltage-regulation loop compensation with 55µS small-signal gain and 5X large-signal gain; output range 0V to 4.95V. |
| 6 | AGND | power_in | Analog ground connection for signal bypass capacitors, compensation networks, and analog circuit returns; star-connected with PGND to minimize differential voltage. |
| 7 | VINAC | input | Input AC voltage sense from rectified mains voltage divider with brownout threshold at 1.39V and dropout threshold at 0.35V; input range 0V to 6V. |
| 8 | HVSEN | input | High voltage output sense for FailSafe overvoltage protection with 4.87V fault threshold and 4.67V clear threshold; triggers PWMCNTL output when above 2.5V. |
| 9 | PWMCNTL | tri_state | Open-drain PWM control output for downstream converter enable/disable; pulled low when HVSEN exceeds 2.5V with no FailSafe overvoltage or phase-fail condition. |
| 10 | CS | input | Current sense input for cycle-by-cycle overcurrent protection with -200mV threshold in dual-phase mode and -166mV in single-phase mode; 100ns blanking after gate transitions. |
| 11 | GDB | output | Gate drive output for phase B power MOSFET with 1A source and 1.8A sink capability; output voltage clamped at 13.5V nominal. |
| 12 | VCC | power_in | Bias supply voltage input from regulated 14V to 21V source with maximum 20mA input current; bypass with 0.1µF ceramic capacitor located close to pin. |
| 13 | PGND | power_in | Power stage ground connection for gate drive and power supply return; star-connected with AGND to minimize DC and high-frequency voltage differential. |
| 14 | GDA | output | Gate drive output for phase A power MOSFET with 1A source and 1.8A sink capability; output voltage clamped at 13.5V nominal. |
| 15 | VREF | power_in | Voltage reference output providing regulated 6.00V ±0.18V for device internal circuits and external biasing with ±2mA load current capability. |
| 16 | ZCDA | input | Zero-current detection input for phase A with 1.0V falling threshold and 1.7V rising threshold; input clamped between 0V and 3V. |
