The LM2596HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an ADJ output version.


1. 3.3V, 5V, 12V and adjustable output versions

2. Guaranteed 3A output current

3. Adjustable version output voltage range,1.23V to57V±4% max over line and load conditions

4. 150 kHz fixed frequency internal oscillator

5. TTL shutdown capability, low power standby mode

6. High efficiency

7. Uses readily available standard inductors

8. Thermal shutdown and current limit protection

9. Wide input voltage range up to 60V

10. Requires only 4 external components
