Texas Instruments LM2671 SIMPLE SWITCHER Power Converter High Efficiency 500mA Step-Down Voltage Regulator with Features LM2671LD-ADJ

The LM2671LD-ADJ is a high-efficiency step-down voltage regulator from Texas Instruments, capable of delivering up to 500 mA of output current. It features an adjustable output voltage range from 1.21 V to 37 V, with a maximum output voltage tolerance of ±1.5% under specified conditions. The device operates with a wide input voltage range of 8 V to 40 V and utilizes a fixed internal oscillator frequency of 260 kHz, allowing for smaller external components compared to lower frequency regulators. This regulator is designed for simplicity, requiring only five external components for operation, and is compatible with standard inductors available from various manufacturers. Additional features include thermal shutdown, current limit protection, soft-start functionality, and TTL shutdown capability, which helps in reducing power consumption during standby mode. The LM2671LD-ADJ is available in a 16-pin WSON package and is suitable for applications requiring efficient power conversion, such as in battery-powered devices and as a pre-regulator for linear regulators.
