STMicroelectronics · DC-DC Converters · SOIC-8
A5973D013TR from STMicroelectronics, in a SOIC-8. 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 | OUT | power_out | Regulator output; the OUT pin DC voltage is rated -1 V to 40 V (-5 V to 40 V peak at t = 0.1 s), and maximum output current is limited internally. |
| 2 | SYNCH | input | Master/slave synchronization input with an absolute range of -0.3 V to 4 V, where a high input needs at least 2.5 V (VREF) and a low input must be 0.74 V or less. |
| 3 | INH | input | Active-high logic inhibit that disables the device when above 2.2 V and enables it below 0.8 V; it must be grounded if unused, and when left open an internal pull-up disables the device. |
| 4 | COMP | passive | Error amplifier output used for frequency compensation of the control loop. |
| 5 | FB | input | Feedback input with an analog pin rating of 4 V; connecting it directly to the output gives 1.23 V, and an external resistive divider is required for higher output voltages. |
| 6 | VREF | power_out | 3.3 V (±2%) reference voltage output that needs no capacitor for stability. |
| 7 | GND | power_in | Ground reference for the device; the exposed pad should be connected to an extended ground plane to reduce thermal resistance. |
| 8 | VCC | power_in | Unregulated DC input voltage, operating from 4 V to 36 V with an absolute maximum of 40 V. |
