TL2575HV-05IKTTR

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

TL2575HV-05IKTTR from Texas Instruments, in a TO-263-5. 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 VIN power_in Supply input pin; the TL2575HV is specified for a recommended supply of 4.75 V to 60 V (absolute maximum 60 V).
2 OUTPUT output Regulated output pin driven by the internal 1-A switch, with the output voltage to GND rated at -1 V minimum in steady state.
3 GND power_in Ground pin for the regulator, serving as the return for the input and output circuits.
4 FEEDBACK input Feedback input: connect to VOUT for the fixed-voltage TL2575, or connect between two adjustment resistors for the adjustable-voltage TL2575.
5 ON/OFF input Manual shutdown input; the ON/OFF input voltage range is -0.3 V to VIN.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
