Product Summary

The TL2575HV-05IKV is a simple step-down switching voltage regulator. The TL2575HV-05IKV greatly simplify 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 of up to 60 V (HV version) and available in fixed output voltages of 3.3 V, 5 V, 12 V, 15 V, or an adjustable-output version, the TL2575HV-05IKV 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. The applications of the TL2575HV-05IKV include Simple High-Efficiency Step-Down (Buck) Regulators, Pre-Regulators for Linear Regulators, On-Card Switching Regulators, Positive-to-Negative Converters (Buck-Boost).
