LT1935ES5#TRMPBF

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

LT1935ES5#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 the Schottky diode here, and minimize the trace area at this pin to reduce EMI.
2 GND power_in Ground pin: tie directly to the local ground plane.
3 FB input Feedback pin with a 1.265V reference: connect the resistive divider tap here, keep the trace at FB short, and set VOUT = 1.265V(1 + R1/R2).
4 SHDN input Shutdown pin: tie to 1.8V or more to enable the device and ground it to shut down; it also provides the soft-start function.
5 VIN power_in Input supply pin that must be locally bypassed; the device operates from a 2.3V to 16V input range.
