The LM2576HVR-12 with DC-DC Converters is a step-down adjustable (fixed) 1.23V, 37V, 3A TO-263-5 RoHS manufactured by HTC Korea. It is a high performance switching regulator that features low output noise, wide output range from 1.23V to 40V and high switching frequency up to 500 kHz. This regulator is suitable for a variety of applications that requires a highly regulated output from a wide input voltage range. It also has low-profile surface mount design that allows for easy high-density installations in confined spaces. This regulator is also designed to reduce external component count and minimize the number of settings required for operation. It also features excellent line/load regulations, low output noise, and an internal soft start. It is also RoHS compliant and suitable for many applications, such as industrial control, communication equipment, and consumer electronics.
