DC Switching Voltage Regulators

LM2593HVT-ADJ/NOPB Description

The LM2593HVT-ADJ/NOPB from Texas Instruments is a high-efficiency, adjustable-output buck (step-down) switching voltage regulator capable of delivering up to 2A of continuous output current. Part of the SIMPLE SWITCHER® series, it operates over a wide 4.5V to 60V input range, making it suitable for industrial, automotive, and telecom applications where input voltage fluctuations are common. The output voltage is adjustable from 1.2V to 57V, providing flexibility for diverse power supply designs. With a fixed 150kHz switching frequency, it balances efficiency and component size, reducing the need for large external filters. The device is housed in a TO-220-7 through-hole package, ensuring robust thermal performance and ease of prototyping.
