MAX5974AETE+T from Analog Devices Inc Maxim Integrated, in a TQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DT | passive | Dead-time programming resistor connection; resistor RDT from DT to GND sets the dead time between the NDRV and AUXDRV signals. |
| 2 | DITHER/SYNC | input | Frequency dithering programming or synchronization input; a capacitor to GND and a resistor to RT set spread-spectrum dithering, or the pin takes the external sync pulse to synchronize the oscillator (synchronization up to 1.2MHz per the features list). |
| 3 | RT | passive | Switching frequency programming resistor connection; resistor RRT from RT to GND sets the PWM switching frequency (100kHz to 600kHz programmable per the features list). |
| 4 | FFB | input | Frequency foldback threshold programming input; a resistor to GND sets the output average current threshold below which the switching frequency folds back to 1/2 of its original value, and connecting it to GND disables foldback. |
| 5 | COMP | passive | Transconductance amplifier output and PWM comparator input, level shifted down to the PWM comparator inverting input, and actively pulled low by the controller after shutdown. |
| 6 | FB | input | Transconductance amplifier inverting input. |
| 7 | GND | power_in | Signal ground. |
| 8 | CSSC | input | Current sense with slope compensation input; a resistor from CSSC to CS programs the amount of slope compensation. |
| 9 | CS | input | Current-sense input for average current sense and cycle-by-cycle current limit, with a 400mV peak current-limit trip voltage and a -100mV reverse current-limit trip voltage. |
| 10 | PGND | power_in | Power ground that serves as the return path for the gate-driver switching currents. |
| 11 | NDRV | output | Main switch gate-driver output. |
| 12 | AUXDRV | output | pMOS active clamp switch gate-driver output, which can also drive a pulse transformer for synchronous flyback applications. |
| 13 | IN | power_in | Converter supply input with wide UVLO hysteresis; the features list an internal 18V zener clamp on the supply input. |
| 14 | EN | input | Enable input; the gate drivers are disabled and the device is in low-power UVLO mode when EN is below VENF, and above VENR the device checks other enable conditions. |
| 15 | DCLMP | input | Feed-forward maximum duty-cycle clamp programming input; a resistive divider from the input supply to GND sets the maximum duty cycle inversely proportional to the input supply voltage, with an 80% maximum limit per the features list. |
| 16 | SS | passive | Soft-start programming capacitor connection; the capacitor sets the soft-start period and hiccup-mode restart time, and a resistor to GND can set DMAX below 75%. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
