TL2575HV-05-Q1

illustrate

The TL2575HV-33 and TL2575HV-05 greatly simplify the design of switching power supplies required to provide all the convenience required for the active role of step-down (buck) switching regulator integrated circuits. Accepting a wide input voltage range of up to 60 V at 3.3 V or 5 V, the TL2575HV-33 and TL2575HV-05 fixed output voltages can boast a complete switch with excellent line and load delivering 1 load current to a lean, regulated one. The device also provides internal frequency compensation, fixed frequency oscillator, cycle-by-cycle current limit, and thermal shutdown. In addition, manual shutdown can also be passed through the external ON/OFF terminal.

The TL2575HV-33 and TL2575HV-05 represent superior alternatives to popular three-terminal linear regulators.
