The LM2576T-ADJ DC-DC Converters TO-220 RoHS manufactured by Huaguan is a low-cost, monolithic, switch-mode power supply, capable of delivering up to 2A from an input voltage of 3-40V DC. The output voltage can be adjusted from 1.23V to 37V DC. The device operates at a fixed frequency of 150kHz, allowing for the use of small, surface-mount components. It features a low Ripple-Feedback-Control (RBC) design which provides excellent line and load regulation. Additional features include floating output, current limiting, short-cycle protection, and thermal overload protection. The LM2576T-ADJ also includes an enable pin that can be used to turn the output off when the device is not in use.
