Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INV. INPUT | input | Inverting input of the error amplifier, with recommended common-mode input voltage of 1.8 to 3.4 V. |
| 2 | N.I. INPUT | input | Non-inverting input of the error amplifier, with recommended common-mode input voltage of 1.8 to 3.4 V. |
| 3 | OSC. OUTPUT | output | Oscillator output pin, which carries the oscillator waveform (oscillation range 100 Hz to 300 kHz). |
| 4 | +C.L. SENSE | input | Positive input of the current limit amplifier, with differential input to pin 5 limited to -0.3 to 0.3 V and a threshold of about 200 mV. |
| 5 | -C.L. SENSE | input | Negative input of the current limit amplifier, with differential input to pin 4 limited to -0.3 to 0.3 V. |
| 6 | RT | passive | Oscillator timing resistor connection, recommended 1.8 to 100 kOhm. |
| 7 | CT | passive | Oscillator timing capacitor connection, recommended 1 to 1000 nF. |
| 8 | GROUND | power_in | Ground reference for the device. |
| 9 | COMPENSATION | passive | Error amplifier output for loop compensation, which feeds the PWM comparator. |
| 10 | SHUTDOWN | input | Shutdown input that turns off the outputs, with a threshold typically of 0.8 V (0.5 to 1.2 V). |
| 11 | EA | passive | Emitter of output transistor A, rated up to 50 mA per output. |
| 12 | CA | passive | Collector of output transistor A, with collector voltage 0 to 40 V and 50 mA recommended output current. |
| 13 | CB | passive | Collector of output transistor B, with collector voltage 0 to 40 V and 50 mA recommended output current. |
| 14 | EB | passive | Emitter of output transistor B, rated up to 50 mA per output. |
| 15 | +VIN | power_in | Positive supply input, recommended 8 to 40 V (absolute maximum 42 V). |
| 16 | VREF | power_out | 5 V reference voltage output (4.8 to 5.2 V), recommended load 0 to 20 mA. |
