The LM2594DADJR2G from On Semiconductor is a monolithic integrated circuit designed for easy and convenient step-down (buck) switching regulator designs. It is capable of driving a 0.5 A load with excellent line and load regulation.
This device features an adjustable output voltage range from 1.23 V to 37 V and operates at a fixed switching frequency of 150 kHz, allowing for smaller filter components. Key electrical specifications include a wide input voltage range up to 40 V and a guaranteed 0.5 A output load current. It also includes features like TTL shutdown capability and a low power standby mode with a typical current of 50 µA.
For protection, the LM2594DADJR2G incorporates switch cycle-by-cycle current limit and thermal shutdown. It is internally compensated to minimize external components, simplifying power supply design. The regulator is housed in a standard 8-Lead Surface Mount SOIC package, suitable for various on-card applications.
Applications include simple high-efficiency step-down regulators, efficient pre-regulators for linear regulators, and positive to negative converters (buck-boost). The device is Pb-Free and has a Moisture Sensitivity Level (MSL) of 1.
