LT1931AES5#TRMPBF
Analog Devices · DC-DC Converters · TSOT-23-5
LT1931AES5#TRMPBF from Analog Devices, in a TSOT-23-5. 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 | SW | output | Switch pin: connect the inductor and catch diode here, and minimize the trace area at this pin to keep EMI down. |
| 2 | GND | power_in | Ground: tie directly to the local ground plane. |
| 3 | NFB | input | Feedback pin with a reference voltage of -1.255V: connect the resistive divider tap here, minimize trace area, and note the NFB bias current flows out of the pin. |
| 4 | SHDN | input | Shutdown pin: tie to 2.4V or more to enable the device and ground to shut it down. |
| 5 | VIN | power_in | Input supply pin that must be locally bypassed; the datasheet gives a wide input range of 2.6V to 16V. |
