The LM2576D2T-ADJ is a step-down switching regulator capable of delivering a maximum output current of 3.0 A. It features an adjustable output voltage range from 1.23 V to 37 V with a guaranteed tolerance of ±4% under specified conditions. The device operates efficiently with a wide input voltage range of 7 V to 40 V, making it suitable for various applications, including as a pre-regulator for linear regulators and in on-card switching power supplies. This regulator is designed to minimize the number of external components required, needing only four for operation, which simplifies the overall design process. It includes features such as thermal shutdown and cycle-by-cycle current limiting for protection against fault conditions. The internal oscillator operates at a fixed frequency of 52 kHz, and the device supports TTL shutdown capability, allowing for low power standby operation. The LM2576D2T-ADJ is available in a D2PAK package and is moisture sensitivity level (MSL) 1 rated, indicating it is suitable for standard handling and assembly processes. Its high efficiency compared to linear regulators makes it a viable choice for applications where heat dissipation is a concern.
