LM2575 Adjustable Voltage Regulators

Texas Instruments LM2575 Adjustable Voltage Regulators incorporate an integrated switch capable of delivering 1A of load current with excellent line and load regulation. These devices simplify the design of switching power supplies by providing all the active functions needed for a step-down (buck) switching regulator in an integrated circuit. The Texas Instruments LM2575 voltage regulators offer internal frequency compensation, a fixed-frequency oscillator, cycle-by-cycle current limiting, and thermal shutdown. These regulators represent a superior alternative to popular three-terminal linear regulators. Due to its high efficiency, it significantly reduces the size of the heat sink, and in many cases, no heat sink is required.
