LT1931IS5#TRPBF

Analog Devices · DC-DC Converters · TSOT-23-5

LT1931IS5#TRPBF 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 passive Switch pin where the inductor/diode connect; keep trace area minimal to reduce EMI (abs max -0.4V to 36V).
2 GND power_in Ground pin, connected directly to the local ground plane.
3 NFB input Negative feedback pin with -1.255V reference; connect the resistive divider tap here, keep trace area minimal, NFB bias current flows out of the pin (abs max -2V).
4 SHDN input Active-low shutdown pin; tie to 2.4V or more to enable the device, ground to turn it off (abs max 16V).
5 VIN power_in Input supply pin that must be locally bypassed; operating up to 16V (minimum operating voltage 2.45V typ, 2.6V max).
