Frequently Asked Questions
What is the output voltage range of the LM2596T-ADJ?
The LM2596T-ADJ features an adjustable output voltage range from 1.23V to 37V, set by an external resistor divider connected to the feedback pin. This flexibility allows designers to target virtually any output voltage within the range using standard resistor values.
What is the maximum input voltage and output current for the LM2596T-ADJ?
The LM2596T-ADJ accepts an input voltage from 4.5V up to 40V and can supply a continuous output current of up to 3A. The device operates at a fixed 150kHz switching frequency, which simplifies external filter design and reduces component size.
What protection features does the LM2596T-ADJ include?
The LM2596T-ADJ integrates thermal shutdown protection that disables the device when the junction temperature exceeds safe limits, as well as cycle-by-cycle current limiting to protect against output short-circuit conditions. These built-in protections improve system reliability without requiring additional external components.
What are typical applications for the LM2596T-ADJ?
Common applications include industrial DC power supplies, automotive voltage regulators, battery chargers, embedded system power rails, and pre-regulation stages before low-dropout regulators. Its adjustable output and high efficiency make it suitable for any system requiring a robust step-down converter delivering up to 3A.
