These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version. The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation.

Create a custom design using the LM2596 with the WEBENCH Power Designer.

Thermal shutdown and current-limit protection.

Uses readily available standard inductors.

Low power standby mode, I Q, typically 80 ♚.

150-kHz fixed-frequency internal oscillator.
