LM2596S-12 TO-263-5 12V 3A DC-DC Buck Switching Regulator IC

LM2596S-12 TO-263-5 12V 3A DC-DC Step-Down (Buck) Voltage Regulator IC

The LM2596S-12 is a switching DC-DC step-down (buck) voltage regulator designed to convert higher input voltages into a fixed 12V output. With an output current capability of up to 3A, this device is widely used in industrial power supplies, automotive applications, networking equipment, and embedded systems.

Thanks to its TO-263-5 (D2PAK) package, the LM2596S-12 provides efficient heat dissipation for high-power applications. Its fixed 150kHz switching frequency, built-in power switch, current limiting, and thermal shutdown features enable efficient, reliable, and compact DC-DC power supply designs.
