TL494CPWR from Texas Instruments, in a TSSOP-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 | 1IN+ | input | Error amplifier 1 non-inverting input; common-mode voltage range -0.3V to VCC-2V. |
| 2 | 1IN- | input | Error amplifier 1 inverting input; common-mode voltage range -0.3V to VCC-2V. |
| 3 | FEEDBACK | input | PWM feedback input for pulse-width modulation control with input threshold voltage 3.4V at zero duty cycle. |
| 4 | DTC | input | Dead-time control comparator input that adjusts minimum dead time from 3% (0V input) to 100% (3.3V input). |
| 5 | CT | passive | External oscillator timing capacitor terminal (range 0.47nF to 10000nF) for frequency setting in conjunction with RT. |
| 6 | RT | passive | External oscillator timing resistor terminal (range 1.8kΩ to 500kΩ) for frequency setting in conjunction with CT. |
| 7 | GND | power_in | Ground reference connection to negative power supply. |
| 8 | C1 | output | MOSFET output 1 collector/drain terminal with open-drain structure capable of 200mA source/sink current. |
| 9 | E1 | output | MOSFET output 1 emitter/source terminal with open-drain structure capable of 200mA source/sink current. |
| 10 | E2 | output | MOSFET output 2 emitter/source terminal with open-drain structure capable of 200mA source/sink current. |
| 11 | C2 | output | MOSFET output 2 collector/drain terminal with open-drain structure capable of 200mA source/sink current. |
| 12 | VCC | power_in | Positive power supply input with recommended operating range 7V to 40V and absolute maximum rating of 41V. |
| 13 | OUTPUT CTRL | input | Output control input that selects single-ended/parallel mode (connect to GND) or push-pull mode (connect to REF). |
| 14 | REF | output | Internal 5V reference voltage regulator output with ±5% tolerance providing 10mA load current capacity and short-circuit protection. |
| 15 | 2IN- | input | Error amplifier 2 inverting input; common-mode voltage range -0.3V to VCC-2V. |
| 16 | 2IN+ | input | Error amplifier 2 non-inverting input; common-mode voltage range -0.3V to VCC-2V. |
