TL594CDR from Texas Instruments, in a SOIC-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 | Non-inverting input of Error Amplifier 1, accepts common-mode voltage from -0.3V to VCC-2V |
| 2 | 1IN- | input | Inverting input of Error Amplifier 1, accepts common-mode voltage from -0.3V to VCC-2V |
| 3 | FEEDBACK | input | Feedback input pin for PWM comparator, typical operation at 2.5V with zero duty-cycle threshold at 3.4V to 4.5V |
| 4 | DTC | input | Dead-time control comparator input, 0-3.3V input controls dead-time from 3% to 100% of switching period |
| 5 | CT | passive | Timing capacitor terminal for oscillator frequency setting, typically 0.47nF to 10µF |
| 6 | RT | passive | Timing resistor terminal for oscillator frequency setting, typically 1.8kΩ to 500kΩ |
| 7 | GND | power_in | Ground reference connection point, 0V |
| 8 | C1 | output | Drain terminal of MOSFET Output 1, open-drain output rated 40V maximum with 200mA maximum drain current |
| 9 | E1 | output | Source terminal of MOSFET Output 1, can source or sink up to 200mA with saturation voltage <1.3V in common-source configuration |
| 10 | E2 | output | Source terminal of MOSFET Output 2, can source or sink up to 200mA with saturation voltage <1.3V in common-source configuration |
| 11 | C2 | output | Drain terminal of MOSFET Output 2, open-drain output rated 40V maximum with 200mA maximum drain current |
| 12 | VCC | power_in | Positive power supply, operating range 7V to 40V with recommended 7V minimum for internal circuit operation |
| 13 | OUTPUT CTRL | input | Output control input selecting single-ended mode (0V, ground) or push-pull mode (Vref ~5V) |
| 14 | REF | output | 5V reference regulator output, ±1% initial accuracy (4.95V-5.05V) with maximum 10mA available load current |
| 15 | 2IN- | input | Inverting input of Error Amplifier 2, accepts common-mode voltage from -0.3V to VCC-2V |
| 16 | 2IN+ | input | Non-inverting input of Error Amplifier 2, accepts common-mode voltage from -0.3V to VCC-2V |
