Texas Instruments · AC-DC Controllers And Regulators · SOIC-16

TL594IDR 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 1IN+ input Noninverting input to error amplifier 1, with common-mode input voltage range from −0.3V to VCC − 2V.
2 1IN− input Inverting input to error amplifier 1, with common-mode input voltage range from −0.3V to VCC − 2V.
3 FEEDBACK input Feedback input to PWM comparator with input threshold voltage for zero duty cycle between 3.4V and 4.5V.
4 DTC input Dead-time control comparator input with input threshold voltage between 2.5V and 3.3V at maximum duty cycle, providing dead-time control from 3% to 100%.
5 CT passive Capacitor terminal for setting oscillator frequency with timing capacitor values from 0.47nF to 10000nF.
6 RT passive Resistor terminal for setting oscillator frequency with timing resistor values from 1.8kΩ to 500kΩ.
7 GND power_in Ground (negative supply reference).
8 C1 output Drain terminal of MOSFET output 1, with open-drain output capable of sinking or sourcing up to 200mA.
9 E1 output Source terminal of MOSFET output 1, with open-source output capable of sinking or sourcing up to 200mA.
10 E2 output Source terminal of MOSFET output 2, with open-source output capable of sinking or sourcing up to 200mA.
11 C2 output Drain terminal of MOSFET output 2, with open-drain output capable of sinking or sourcing up to 200mA.
12 VCC power_in Positive supply voltage with operating range from 7V to 40V.
13 OUTPUT CTRL input Output control input that selects single-ended or push-pull operation, tied to ground for single-ended mode or to REF for push-pull mode.
14 REF output 5V reference regulator output with nominal voltage of 5.0V and output regulation from 6mV to 35mV.
15 2IN− input Inverting input to error amplifier 2, with common-mode input voltage range from −0.3V to VCC − 2V.
16 2IN+ input Noninverting input to error amplifier 2, with common-mode input voltage range from −0.3V to VCC − 2V.
