UC3867N
Texas Instruments · DC-DC Converters · PDIP-16
UC3867N from Texas Instruments, in a PDIP-16. 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 | 5V | power_out | 5V generator output that biases internal circuits and supplies up to 10mA for external use, 4.8V to 5.2V over 12V to 20V Vcc. |
| 2 | NI | input | Non-inverting input of the error amplifier, with absolute maximum input range of -0.4V to 7V. |
| 3 | INV | input | Inverting input of the error amplifier, with absolute maximum input range of -0.4V to 7V. |
| 4 | E/A Out | output | Error amplifier output driving the VCO, with absolute maximum output current of ±2mA. |
| 5 | Sig Gnd | power_in | Signal ground, the reference for all voltages in the datasheet. |
| 6 | Range | passive | VCO range programming pin, set by a resistor (7.15k in the test conditions) to program the VCO frequency range. |
| 7 | Rmin | passive | VCO minimum-frequency programming resistor pin (86.6k in the test conditions). |
| 8 | Cvco | passive | VCO timing capacitor pin (1nF in the test conditions). |
| 9 | RC | passive | One-shot timing resistor/capacitor pin that sets the maximum pulse width (1000ns typical). |
| 10 | Zero | input | Zero detection comparator input with 0.5V typical threshold that terminates the one-shot pulse; absolute maximum input -0.4V to 7V. |
| 11 | A Out | output | Totem-pole FET driver output A with 1A peak drive; absolute maximum source or sink current 0.5A. |
| 12 | Pwr Gnd | power_in | Power ground for the output FET drivers; absolute maximum voltage relative to signal ground ±0.2V. |
| 13 | Vcc | power_in | Supply input with undervoltage lockout; absolute maximum 22V. |
| 14 | B Out | output | Totem-pole FET driver output B with 1A peak drive; absolute maximum source or sink current 0.5A. |
| 15 | Fault | input | Fault comparator input with 3.00V typical threshold that latches and forces outputs low; absolute maximum input -0.4V to 7V. |
| 16 | Soft-Ref | bidirectional | Soft-start, restart delay and system reference pin with 5.00V typical precision reference voltage. |
