Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INPP | input | Non-inverting input of first error amplifier; accepts input voltage range −0.3V to Vcc−2.0V. |
| 2 | INNP | input | Inverting input of first error amplifier; accepts input voltage range −0.3V to Vcc−2.0V. |
| 3 | INfc | input | PWM feedback comparator input; zero duty cycle threshold voltage 4.0−4.5V. |
| 4 | DTC | input | Dead time control input; adjusts maximum duty cycle with input voltage 0−5.25V. |
| 5 | CT | passive | Oscillation frequency adjustment capacitor pin; recommended value range 0.00047−10µF. |
| 6 | RT | passive | Oscillation frequency adjustment resistor pin; recommended value range 1.8kΩ−500kΩ. |
| 7 | GND | power_in | Ground reference. |
| 8 | C1 | output | First output transistor collector; maximum voltage rating 40V. |
| 9 | E1 | output | First output transistor emitter; maximum source/sink current ±200mA. |
| 10 | E2 | output | Second output transistor emitter; maximum source/sink current ±200mA. |
| 11 | C2 | output | Second output transistor collector; maximum voltage rating 40V. |
| 12 | Vcc | power_in | Power supply input; recommended operating voltage range 7.0V to 40V. |
| 13 | OUTcon | input | Output control pin; selects push-pull mode (0−0.4V) or single-ended mode (2.4V to Vref). |
| 14 | Vref | power_out | Internal reference voltage output; 4.75−5.25V (typical 5.0V) at 1.0mA load current. |
| 15 | INPP | input | Inverting input of second error amplifier; accepts input voltage range −0.3V to Vcc−2.0V. |
| 16 | INNP | input | Non-inverting input of second error amplifier; accepts input voltage range −0.3V to Vcc−2.0V. |
