LT1930ES5#TRPBF

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

LT1930ES5#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, to which the inductor and diode are connected; minimize trace area here to reduce EMI, with the absolute maximum SW voltage range being -0.4V to 36V.
2 GND power_in Ground pin, to be tied directly to the local ground plane.
3 FB input Feedback pin for the resistive divider tap, with a reference voltage of 1.255V and VOUT = 1.255V(1 + R1/R2); keep trace area minimal and limit current into FB to ±1mA (absolute maximum), with FB voltage rated at 2.5V maximum.
4 SHDN input Shutdown pin: tie to 2.4V or more to enable the device and ground to shut it down, with a maximum SHDN voltage of 10V.
5 VIN power_in Input supply pin that must be locally bypassed, with VIN rated to 16V maximum and a minimum operating voltage of 2.6V.
