Frequently Asked Questions
What is the output voltage range of the LM2596T-ADJ/NOPB?
The LM2596T-ADJ/NOPB provides an adjustable output voltage from 1.2V to 37V, set by an external resistor divider. The input voltage range is 4.5V to 40V, and the device delivers up to 3A continuous output current with a fixed 150kHz switching frequency.
What are the typical applications for the LM2596T-ADJ/NOPB?
This device is commonly used in industrial power supplies, battery chargers, automotive electronics, LED drivers, and point-of-load DC-DC converters. Its adjustable output and 3A rating make it suitable for powering microcontrollers, FPGAs, sensors, and communication modules in embedded and telecommunications systems.
What package does the LM2596T-ADJ/NOPB come in, and is it RoHS compliant?
The LM2596T-ADJ/NOPB is housed in a TO-220 5-pin through-hole package, which provides excellent thermal performance for high-current applications. It is RoHS compliant (Pb-free, e3 JEDEC-609 code), making it suitable for environmentally conscious designs.
How does the LM2596T-ADJ/NOPB compare to fixed-output versions like LM2596T-5.0?
Unlike fixed-output variants such as the LM2596T-5.0 (5V) or LM2596T-3.3 (3.3V), the ADJ version allows output voltage adjustment from 1.2V to 37V via an external resistor network. This flexibility comes at the cost of two additional passive components but enables a single design to support multiple output voltage requirements.
