DC Switching Voltage Regulators

LM2590HVS-5.0/NOPB Description

The LM2590HVS-5.0/NOPB from Texas Instruments is a high-efficiency, fixed-output 5V, 1A buck (step-down) switching voltage regulator designed for rugged industrial and automotive applications. Part of the SIMPLE SWITCHER® series, it operates over a wide 4.5V to 60V input range, making it ideal for systems requiring stable power from variable or high-voltage sources. With a 150kHz switching frequency, it balances efficiency and component size, while its non-synchronous rectification simplifies design. The device is housed in a DDPAK surface-mount package, ensuring robust thermal performance and reliability. Compliant with ROHS3 and REACH, it meets stringent environmental standards.

LM2590HVS-5.0/NOPB Features

• Wide Input Range (4.5V–60V): Supports high-voltage inputs, including automotive and industrial power rails.
• Fixed 5V Output: Delivers a stable 1A current with ±4% tolerance, eliminating the need for external feedback components.
• High Efficiency (Up to 80%): Minimizes power dissipation with integrated 150kHz PWM control.
• Robust Design: MSL3 (168-hour) moisture sensitivity and DDPAK package enhance durability in harsh environments.
• Simplified Layout: Non-synchronous topology reduces BOM complexity compared to synchronous alternatives.
• Protections: Includes thermal shutdown and current limiting for fault resilience.

LM2590HVS-5.0/NOPB Applications

• Automotive Systems: Powers infotainment, sensors, and ECUs from 12V/24V batteries.
• Industrial Equipment: Ideal for PLCs, motor controllers, and factory automation with unstable input voltages.
• Telecom/Networking: Provides regulated 5V for routers, switches, and PoE modules.
• Consumer Electronics: Used in set-top boxes, displays, and portable devices requiring efficient step-down conversion.
• Renewable Energy: Converts higher DC voltages (e.g., solar panels) to 5V for control circuits.
