LM2592HVS-5.0

LM2592HVS-5.0 is a 3‑A, fixed‑output step‑down (buck) regulator from the LM2592 family with a high‑voltage capability. The HVS suffix denotes a high‑voltage version (wide input range) and the 5.0 indicates a fixed 5.0‑V output.
Key points:
- Topology: buck regulator with current‑mode PWM control and an internal switch.
- Output: fixed 5.0 V, up to about 3 A.
- Input range: designed for high input voltages (HVS version typically up to ~60 V).
- External components: requires external inductor, catch diode (Schottky), input/output caps, and bias components.
- Protections: thermal shutdown, current limit, short‑circuit protection; enable/shutdown pin.
- Efficiency: high for a buck converter; performance depends on Vin–Vout, switching frequency, and components.
- Packages: available in standard IC packages (e.g., SO‑8, TO‑220 variants).
Typical use: automotive/industrial power supplies that must convert 9–60 V down to a stable 5 V rail. Always consult the datasheet for exact electrical specs, pinout, and recommended external components.

Here are the main features of the LM2592HVS-5.0 (fixed 5.0 V) version:
- Fixed output: 5.0 V
- Wide input range: up to 60 V (high-voltage version)
- Output current capability: up to 3 A
- Switching frequency: ~52 kHz
- Internal high-side switch with current–mode control
- Cycle-by-cycle current limiting
- Thermal shutdown protection
- Short-circuit/overcurrent protection
- Internal feedback for fixed-output (no external divider required)
- Requires external components: inductor, Schottky catch diode, input/output capacitors
- Simple, pin-compatible with other LM2592 devices
Applications: compact, high-voltage step-down up to 60 V for telecom/industrial automotive environments.

The LM2592HVS-5.0 is supplied in a 5-lead TO-263 (D2PAK) surface-mount power package.

Pin count: 5 pins (also available in 5-lead TO‑220 and TO‑263 packages).
Primary functions:
- VIN — input supply (high‑voltage capable up to ~60 V).
- SWITCH/OUTPUT — internal power switch (connects to inductor; also the heat‑tab).
- GND — circuit ground/reference.
- FEEDBACK — senses output for regulation (on fixed‑5.0 versions the feedback is internally trimmed but the pin is present/used for layout).
- ON/OFF (EN) — logic enable to turn the regulator on or off.
Device summary: LM2592HVS‑5.0 is a fixed 5.0 V, 3 A monolithic step‑down (buck) switching regulator requiring external inductor, diode, and capacitors.

LM2592HVS-5.0 is a 3A, 60V-input fixed-5V buck regulator. Common applications:
- Automotive/vehicle electronics (12V/24V systems)
- Industrial equipment powered from 24–60V DC
- Telecom/network gear needing a 5V rail
- Embedded systems from higher-voltage sources
- Compact 5V supplies from batteries, solar, or utility DC sources

Functional equivalents (3 A, fixed 5.0 V buck switching regulators) include: TI LM2596-5.0, LM2576-5.0, XL2576/XL2596 (common clones) and MP1584-based modules. Note: these are functionally similar but may differ in input-voltage rating, pinout, switching frequency and thermal limits — LM2592HVS is a high-voltage device (up to ~60 V). Always verify datasheets before substituting.
