1-A Simple Step-Down Adjustable Voltage Switching Regulator With Output Enable

The LM2575 greatly simplifies the design of switching power supplies by conveniently providing all the active functions needed for a Step-down (buck) Switching Regulator in an integrated circuit. Accepting a wide input voltage range and available in an adjustable output version, the LM2575 has an integrated Switch capable of delivering 1 A of load current, with excellent line and load regulation. The device also offers internal frequency compensation, a fixed-frequency Oscillator cycle-by-cycle current limiting, and thermal shutdown. In addition, a manual shutdown is available via an external ON/OFF pin. By Texas Instruments
