TL2575HV-12IKTTR Description

The TL2575HV-12IKTTR provides all the active functions needed for an integrated circuit's step-down (buck) switching regulator. It requires four to six external components for operation. It accepts a wide input-voltage range of up to 60 V (TL2575-HV) and is available in fixed output voltages of 3.3 V, 5 V, 12 V, 15 V, or an adjustable output version. The TL2575HV-12IKTTR has an integrated switch capable of delivering 1 A of load current, with excellent line and load regulation.
