Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | AMPERR1+ | input | Non-inverting input of error amplifier 1. |
| 2 | AMPERR1- | input | Inverting input of error amplifier 1. |
| 3 | INCPWM | input | PWM comparator input used to set the pulse-width comparison level. |
| 4 | CONTDE | input | Dead-time control input whose threshold voltage (3 V at 0% duty cycle, 3.3 V typical) sets the maximum duty cycle. |
| 5 | COSC | passive | Oscillator timing capacitor connection; with ROSC it sets the oscillation frequency (10 kHz typical at CT=0.01uF, RT=12k). |
| 6 | ROSC | passive | Oscillator timing resistor connection; with COSC it sets the oscillation frequency, specified over 80 Hz to 300 kHz. |
| 7 | GND | power_in | Ground reference for the control circuitry. |
| 8 | OUT1 | output | Output transistor 1 pin, rated for 500 mA output current. |
| 9 | GNDOUT1 | power_in | Output ground 1 for output transistor 1. |
| 10 | GNDOUT2 | power_in | Output ground 2 for output transistor 2. |
| 11 | OUT2 | output | Output transistor 2 pin, rated for 500 mA output current. |
| 12 | VCC | power_in | Supply voltage input; the absolute maximum supply voltage is 40 V. |
| 13 | CONOUT | input | Output control input that selects push-pull or single-ended operation of the output transistors. |
| 14 | VREF | power_out | 5 V reference voltage output (4.95 V to 5.05 V at 1 mA). |
| 15 | AMPERR2- | input | Inverting input of error amplifier 2. |
| 16 | AMPERR2+ | input | Non-inverting input of error amplifier 2. |
