The LM2576HVS-ADJ is a high-voltage version of the adjustable voltage regulator from the LM2576 series, designed for step-down (buck) conversion. It comes in a 5-pin package. Here are the pin functions:
1. VIN: This is the input pin where the unregulated voltage is supplied. It can handle a higher voltage compared to the non-HVS version.
2. VOUT (SWITCH): This pin is the output switch. It connects to the inductor in the buck converter setup.
3. GROUND (GND): This is the ground reference for the device.
4. FEEDBACK (FB): This pin is used to regulate the output voltage. An external resistor divider network is connected to this pin to set the desired output voltage.
5. ON/OFF: This pin is used to enable or disable the device. Grounding this pin turns the regulator off, while leaving it open or connecting it to a high level enables it.
