Descripción general

Description

LM2591HVS-ADJ is a high-voltage, adjustable-output buck regulator. Key points:
- High input rating: up to about 60V, for step-down from a higher source.
- Output: adjustable via external resistor divider (uses a 1.23V reference to set Vout).
- Power: integrated switch capable of roughly 3 A continuous load.
- External components: needs inductor, a fast Schottky catch diode, input/output capacitors, and the FB resistor network to set Vout.
- Operation: non-synchronous buck regulator with a fixed switching frequency (typical around 50–60 kHz).
- Protection: current limit and thermal shutdown.
- Interface: enable/shutdown control; straightforward, common in automotive/industrial DC-DC designs.
- Package: available in 8-pin versions (e.g., SOIC/TO-220 variants).
ADJ denotes adjustable output (not fixed). For detailed limits and recommended circuits, consult the TI/National datasheet.

Features

Key features of LM2591HVS-ADJ (High-Voltage Adjustable Buck Regulator):
- 3 A output switch current; suitable for non-synchronous buck conversion.
- High input voltage tolerance: up to 60 V (HV/HVS variant).
- Adjustable output: 1.23 V to 37 V via external resistor divider (ADJ version).
- Fixed switching frequency around 52 kHz; current‑mode control for good transient response.
- Built‑in protections: overcurrent/short‑circuit protection, thermal shutdown, and UVLO.
- Enable/shutdown input to turn device on/off.
- External components required: inductor, Schottky catch diode, input/output capacitors.
- Efficient operation across loads/inputs; simple, low‑parts design.

Package

LM2591HVS-ADJ is the high-voltage, adjustable version in a surface-mount D2PAK (TO-263) package.

Pinout

- Pin count: 5 pins
- Function: High-voltage (up to 60 V) adjustable buck regulator (LM2591HVS-ADJ), 3 A switcher. Requires external inductor, catch diode, and input/output capacitors. Pin roles: Vin, Vout (switch output), GND, FB (feedback), and EN/On-Off (enable).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: TI is an American multinational semiconductor company that designs and manufactures integrated circuits and semiconductors, specializing in analog, power management, and embedded processing devices for electronics.

Application

LM2591HVS-ADJ is a high‑voltage, adjustable buck regulator (60V input, up to 3A). Common applications: automotive power supplies (12–60V to 5V/3.3V), industrial/telecom DC‑DC converters, battery‑powered equipment, solar/battery backup power rails, and general non‑isolated step‑down rails for microcontrollers/DSPs.
