Texas Instruments LM257x SIMPLE SWITCHER® Voltage Regulators
Texas Instruments LM257x SIMPLE SWITCHER® Step-Down Voltage Regulators are high-efficiency devices ranging from 0.5A to 3A output current. TI LM2574 and LM2574HV SIMPLE SWITCHER Step-Down Voltage Regulators provide all the active functions for a step-down (buck) switching regulator capable of driving a 0.5A load with excellent line and load regulation. The LM2575 and LM2575HV step-down voltage regulators provide all the active functions for a step-down (buck) switching regulator capable of driving a 1A load with excellent line and load regulation.
The LM2576 and LM2576HV step-down voltage regulators provide all the active functions for a step-down (buck) switching regulator capable of driving 3A load with excellent line and load regulation. The LM2577 SIMPLE SWITCHER 3A Step-Up Voltage Regulators provide all the power and control functions for step-up (boost), flyback, and forward converter switching regulators. TI LM257x devices are a high-efficiency replacement for popular three-terminal linear regulators.
