Description
The LM2592HVS-5.0 is TI’s fixed-output, high-voltage buck regulator. It is the 5.0 V version of the LM2592HVS family and is designed to step down a wide input voltage (up to 60 V) to a stable 5 V output with up to about 3 A of load current.
Key points
- Input/output: Wide Vin range (roughly 4.5–60 V), fixed 5.0 V output, up to ~3 A.
- Topology: High‑voltage, current‑mode buck regulator with an integrated high-side switch; requires external inductor and a Schottky catch diode (plus input/output capacitors).
- Performance: Typical switching frequency around tens of kHz; efficient operation (roughly 75–90% depending on Vin and load).
- Protections: Current limit, thermal shutdown, undervoltage lockout; enable/shutdown pin for power‑saving.
- Applications: Automotive, industrial, telecom, and other systems needing a robust 5 V rail from a high-voltage supply.
If designing, consult the datasheet for exact pinout, recommended external components, layout guidelines, and application notes.
