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. |
