LM2592HVS-5.0

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.

Key features of LM2592HVS-5.0 (fixed 5V, 2A buck regulator):
- Fixed 5.0 V output; capable of up to 2 A load.
- High-voltage input version: up to 60 V input range (HVS variant).
- Fixed switching frequency around 52 kHz.
- High efficiency operation across load and input conditions.
- Requires only a few external components (external inductor, Schottky catch diode, input/output capacitors); no opto feedback needed.
- Internal switch with current limit and thermal shutdown protection.
- Excellent line and load regulation with fast transient response.
- Available in standard power-pack/SMD options for easy board layout and integration.

Pin count: 8 pins (D8/SO-8 package).
Function: LM2592HVS-5.0 is a fixed‑output, high‑voltage buck switching regulator. It accepts up to 60 V input and provides a regulated 5.0 V output with up to about 2 A load current (requires external inductor and catch diode). Key pins include Vin, GND, SW (switch node to inductor), FB (feedback), EN (enable), and SS/COMP (soft‑start/compensation); remaining pins are NC per package variant.

Manufacturer: Texas Instruments (TI).
Company type: American multinational semiconductor company that designs, manufactures, and sells analog, mixed-signal, and embedded processing integrated circuits for electronics worldwide.

LM2592HVS-5.0 is a high-voltage (up to ≈60V input), 2A step-down regulator with fixed 5V output. Typical applications include:
- Automotive power supplies (12V/24V systems) to 5V rails
