TL2575-05IKTTR

Texas Instruments · DC-DC Converters · TO-263-5

TL2575-05IKTTR from Texas Instruments, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Unregulated DC supply input. Operating range 4.75 V to 40 V (absolute max 42 V) for the TL2575 variant. Bypass with an input capacitor close to the pin.
2 OUTPUT output Switching regulator output. Drives the external inductor / catch diode / output capacitor network to produce the regulated 5-V rail at up to 1 A load current.
3 GND power_in Device ground reference. On the KTT (TO-263) package this pin is also tied to the exposed tab/heat-sink pad for thermal dissipation.
4 FEEDBACK input Regulator feedback sense input. For the fixed-voltage TL2575-05, tie directly to VOUT (5 V nominal). Internal reference is 1.23 V (used only by the adjustable variant).
5 ON/OFF input Active-low manual shutdown input. Pull low (or tie to GND) for normal operation; drive high (up to VIN) to place the device in standby (standby quiescent current typ. 50 µA). Input range -0.3 V to VIN.
