Product details
Overview
LM2592HVS-5.0 from Texas Instruments is a monolithic 150 kHz, 2A step-down (buck) switching voltage regulator with fixed 5.0 V output, 4.5–60 V input range, ±4% output voltage tolerance over line/load/temperature, and integrated thermal shutdown and current limiting. It delivers high-efficiency power conversion in industrial power supplies and automotive pre-regulators.
For engineers reviewing the LM2592HVS-5.0 datasheet, LM2592HVS-5.0 pinout, LM2592HVS-5.0 application, or LM2592HVS-5.0 equivalent, key selection criteria include its 60 V max input rating, 90 μA standby current, TO-220/DDPAK package options, and compatibility with standard Schottky catch diodes and off-the-shelf inductors for rapid buck converter design.
Technical Context
The LM2592HVS-5.0 implements a fixed-frequency current-mode buck topology with internal 150 kHz oscillator, single N-channel MOSFET switch, and built-in error amplifier with feedback sensing at the output pin. Its two-stage current limit and thermal shutdown provide fault protection without external circuitry.
It operates across −40°C to +125°C junction temperature, supports ON/OFF control via Pin 5 (logic-compatible threshold at 1.3 V), and maintains regulation with input as low as 7 V for full 2 A load - enabling robust operation in wide-input industrial and transportation systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±4% (min 4.75 V / max 5.25 V at full load and temperature extremes) |
| Input Voltage Range | 4.5 V to 60 V DC - supports 24 V/36 V/48 V industrial buses and automotive cold-crank transients |
| Max Output Current | 2 A continuous - enables single-chip conversion for mid-power embedded subsystems |
| Switching Frequency | 150 kHz fixed - allows use of compact, low-cost 33–47 μH inductors and standard electrolytic capacitors |
| Quiescent Current | 90 μA in shutdown mode - minimizes battery drain in always-on monitoring circuits |
| Efficiency | 81% typical at VIN = 12 V, VOUT = 5 V, IOUT = 2 A - reduces thermal load vs. linear regulators |
| Thermal Protection | Internal thermal shutdown at TJ ≥ +150°C - prevents damage during overload or poor heatsinking |
Pinout & Package
LM2592HVS-5.0 is available in the 5-lead TO-220 (package code KTT) and 5-lead DDPAK (package code NDH) packages. Both feature exposed thermal pads for enhanced heat dissipation and share identical pin functions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +VIN (Pin 1) | Power input | Accepts 4.5–60 V DC; requires local low-ESR bypass capacitor to handle 2 A switching currents |
| Output (Pin 2) | Switch node | Drives external inductor; swings between ~(+VIN − 1.3 V) and ~−0.5 V; connects to cathode of Schottky catch diode |
| Ground (Pin 3) | Power and signal reference | Common return for input/output paths and feedback loop; must be low-impedance PCB plane |
| Feedback (Pin 4) | Regulation sense | Internally tied to output for fixed 5.0 V version; not user-accessible - eliminates external resistor divider |
| ON/OFF (Pin 5) | Enable control | Logic-level shutdown: ≤0.6 V = ON, ≥2.0 V = OFF; draws only 90 μA in shutdown state |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 2 A switch | Eliminates need for external MOSFET and gate driver - reduces BOM count and layout complexity |
| Wide 4.5–60 V input | Supports direct connection to unregulated 24 V/36 V/48 V rails and withstands automotive load-dump surges |
| Fixed 5.0 V output | Guaranteed ±4% accuracy over full temperature and load range - suitable for powering logic, sensors, and analog ICs |
| 150 kHz fixed frequency | Enables predictable EMI filtering and consistent inductor sizing across designs using standard 33–68 μH parts |
| Thermal + current protection | Self-contained fault recovery - no external sensing or latch circuitry required for basic system reliability |
Applications
| Industrial Power Supply | Automotive Pre-Regulator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2596S-5.0 | Higher 150 kHz frequency (same), but rated for 3 A output and includes adjustable version in same package; slightly higher IQ (5 mA active) | Better suited for >2 A loads or designs requiring flexibility between fixed/adjustable outputs | Select when future scalability to 3 A or dual-output variants is needed; requires minor layout revision due to different pinout |
| MP1584EN-LF-Z | 40 V max input (vs. 60 V), 3 A output, 1.5 MHz switching, smaller SO-8EP package; no integrated thermal pad in standard variant | Ideal for space-constrained consumer electronics with lower input voltage requirements | Choose for compact 12 V input systems where PCB area is critical; not suitable for 48 V industrial or automotive applications |
Compared with LM2592HVS-5.0, LM2596S-5.0 offers higher current headroom and pinout flexibility but lacks the 60 V input margin, while MP1584EN-LF-Z enables miniaturization at the cost of input voltage range and thermal robustness - making LM2592HVS-5.0 optimal for ruggedized 24–48 V systems requiring field-proven reliability.

FAQ
What is the maximum input voltage rating for LM2592HVS-5.0?
The LM2592HVS-5.0 has an absolute maximum input voltage rating of 63 V, with guaranteed operation up to 60 V DC. This enables reliable use in 48 V industrial systems and automotive environments subject to load-dump transients. Operation above 60 V risks permanent damage and is outside the device's specified operating conditions.
Does LM2592HVS-5.0 require an external feedback resistor network?
No. The LM2592HVS-5.0 is a fixed-output variant: Pin 4 (Feedback) is internally connected to the output, eliminating the need for external resistors. This simplifies design, improves accuracy by removing resistor tolerance errors, and reduces component count - unlike the adjustable LM2592HV-ADJ version which requires a precision R1/R2 divider.
Can LM2592HVS-5.0 be used in a negative-output (inverting) configuration?
Yes. The LM2592HVS-5.0 can be configured as a positive-to-negative inverter per TI Application Note guidelines. In this topology, the ground pin becomes the negative output, the output pin connects to system ground, and feedback is referenced accordingly. Efficiency and regulation performance remain consistent with buck operation when using appropriate external components.
What thermal management is required for LM2592HVS-5.0 at 2 A load?
At 2 A output with 12 V input, LM2592HVS-5.0 dissipates ~1.4 W. With θJA = 50°C/W (TO-220, no heatsink), junction temperature rise is ~70°C - requiring a minimum ambient of 55°C for safe operation. Use of a small heatsink or copper pour (≥1 in²) reduces θJA significantly; DDPAK versions benefit from soldered thermal pad to inner-layer copper planes.
Is LM2592HVS-5.0 RoHS compliant and lead-free?
Yes. LM2592HVS-5.0 is manufactured in RoHS-compliant, lead-free packages (TO-220 KTT and DDPAK NDH). Texas Instruments confirms full compliance with EU RoHS Directive 2011/65/EU and related exemptions, including Pb-free terminations and halogen-free molding compounds - verified in official TI product change notices and material declarations.
