The LM2594DADJR2G is an IC component manufactured by ON Semiconductor. It is a step-down switching regulator designed to deliver a constant output voltage from a variable input voltage source. This highly efficient device is capable of handling a maximum output current of 0.5 A.
One of the key features of the LM2594DADJR2G is its wide input voltage range, which spans from 4.5 V to 40 V. This makes it suitable for a variety of applications, including automotive and industrial systems. The device operates at a fixed switching frequency of 150 kHz, allowing for easy external component selection.
Another important feature is its ability to provide an adjustable output voltage. By utilizing an external resistor divider network, the output voltage can be precisely set between 1.23 V and 37 V. This flexibility allows the LM2594DADJR2G to accommodate a wide range of load requirements.
The LM2594DADJR2G incorporates a built-in current limit circuitry that safeguards the IC and the load from excessive current draw. This feature ensures the long-term reliability of the device and provides protection against short-circuits and overloads. Furthermore, the IC includes a thermal shutdown mechanism that prevents overheating by turning off the output when the temperature exceeds a specified limit.
To enhance its efficiency, the LM2594DADJR2G features a pulse-width modulation (PWM) control scheme
