概要
Description
The LM2596HVS-ADJ is a high-voltage version of the LM2596 series of DC-DC step-down (buck) voltage regulators. Designed for efficiency, it can step down an input voltage of up to 60 volts to a lower, adjustable output voltage. This makes it suitable for use in a wide range of applications, including battery-powered devices, automotive systems, and industrial equipment.
Key features include a high-efficiency operation of up to 90%, an adjustable output voltage range typically from 1.23V to 37V, and a maximum output current capability of 3A. It operates at a fixed 150 kHz switching frequency, which allows for smaller external components and a more compact design.
The LM2596HVS-ADJ also includes features like thermal shutdown, current limit protection, and an on/off control pin for better power management. It typically requires a few external components to set the desired output voltage and to stabilize the circuit. Overall, the LM2596HVS-ADJ is valued for its robustness, versatility, and efficient performance in high-voltage applications.

Pinout
The LM2596HVS-ADJ is a high-voltage version of the LM2596 series of step-down voltage regulators. It is specifically designed to provide a variable output voltage with an adjustable feature. The device typically comes in a 5-pin TO-220 or TO-263 package.
The pin functions are as follows:
1. Vin: This is the input voltage pin where the power supply is connected. It can handle input voltages up to 60V.
2. Output: This pin provides the regulated output voltage, which can be adjusted via an external resistor divider network.
3. Ground (GND): This is the ground pin and is used as a reference point for all other voltages in the circuit.
4. Feedback (FB): This pin is used to set the output voltage. It is connected to the output via a resistor divider network to provide feedback to the regulator.
5. ON/OFF: This is the shutdown pin. Pulling this pin high will turn off the regulator, reducing the quiescent current to a very low value.
These pins work together to allow the LM2596HVS-ADJ to efficiently convert a high input voltage to a lower, stable output voltage suitable for various electronic applications.
