open-in-new Find other Buck converters (integrated switch)


The TL2575 and TL2575HV devices provide all the active functions needed for a step-down (buck) switching regulator in an integrated circuit. They require four to six external components for operation. They accept a wide input-voltage range of up to 60 V (TL2575-HV) and are available in fixed output voltages of 3.3 V, 5 V, 12 V, 15 V, or an adjustable-output version. The TL2575 and TL2575HV devices have 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.
