The ON Semiconductor LM2595DSADJR4G is a highly efficient, integrated circuit specifically designed as a buck (step-down) voltage regulator. It is capable of driving a 1A load with excellent line and load regulation. The device is a part of the LM2595 series, which are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with high efficiency, lower external parts count, and compact design.

Key Features

• Output Voltage: The device offers an adjustable output voltage range from 1.23V to 37V, which makes it versatile for a wide range of applications.
• High Efficiency: A switch is included on the die along with a standard series of inductors and capacitors to minimize the space and cost of the external components.
• Thermal Shutdown and Current Limit: Protection features include a thermal shutdown mechanism and a current limit to protect the device and the load in the event of an over-temperature or over-current condition.
• Frequency of Operation: It operates at a switching frequency of 150 kHz, which allows for smaller-sized filter components, resulting in a reduction of the overall solution size and cost.
