LT1615IS5#TRPBF

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

LT1615IS5#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 output Switch pin, the collector of the internal NPN power switch; minimize the metal trace area connected to this pin to minimize EMI, and the SW voltage is rated to 36V absolute maximum.
2 GND power_in Ground pin; tie this pin directly to the local ground plane.
3 FB input Feedback pin that sets the output voltage through external resistors R1 and R2, with current into the FB pin limited to 1mA absolute maximum.
4 SHDN input Shutdown pin; tie to 0.9V or higher to enable the device and tie below 0.25V to turn the device off.
5 VIN power_in Input supply pin, rated to 15V absolute maximum for VIN; bypass this pin with a capacitor as close to the device as possible.
