LT3464ETS8#TRPBF

Analog Devices · DC-DC Converters · TSOT-23-8

LT3464ETS8#TRPBF from Analog Devices, in a TSOT-23-8. 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 CTRL input Internal reference override pin that sets the FB voltage externally between 0V and 1.25V when driven below 1.25V, and must be tied above 1.5V (e.g., to VIN) to use the internal 1.25V reference.
2 FB input Feedback pin that the LT3464 regulates to 1.25V (internal reference) or to VCTRL when CTRL is between 0V and 1.25V, with absolute maximum voltage of 6V.
3 OUT output PNP collector output of the output disconnect circuit, which must be bypassed with at least a 0.1µF capacitor to the CAP pin or to ground.
4 GND power_in Ground pin that must be tied directly to the ground plane.
5 CAP power_out PNP emitter and Schottky cathode connected to the output capacitor and optionally to an external phase-lead capacitor, with absolute maximum voltage of 36V.
6 SW output Collector of the internal NPN power switch and Schottky anode, with absolute maximum voltage of 36V, where trace area should be minimized to reduce EMI.
7 VIN power_in Input supply pin operating from 2.3V to 10V (absolute maximum 10V), to be bypassed with a capacitor placed as close to the device as possible.
8 SHDN input Shutdown pin where tying it low (VIL max 0.2V) shuts down the device and tying it high (VIH min 2.3V) enables normal operation, with absolute maximum of 10V.
