The HGSEMI LM2576T-ADJ Step-Down Adjustable DC-DC Converter with a TO-220-5 RoHS package is designed for use in highly efficient regulated power supplies. This converter is capable of delivering high output currents of up to 3 Amps and its wide input voltage range of 40V and output voltage range of 1V to 37V allows for a very wide range of applications. The LM2576T-ADJ DC-DC Converter has a low external component count, low on-resistance output switches, and a high operating frequency of up to 500kHz resulting in minimized overall solution dimension and extremely small PCB area requirements. It is designed to be used with various low and medium power Loads. The LM2576T-ADJ also has very good efficiency, high ripple rejection and good line/load regulation. The device is UL/CSA approved and enables maximum possible efficiency due to its adjustable and synchronous rectifier. It also includes integrated over-voltage, under-voltage, and over-temperature protection features.
