The TL2575HV-33 and TL2575HV-05 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 and available in fixed output voltages of 3.3 V or 5 V, the
TL2575HV-33 and TL2575HV-05 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.
The TL2575HV-33 and TL2575HV-05 represent superior alternatives to popular three-terminal linear regulators.
Due to their high efficiency, the devices significantly reduce the size of the heat sink and, in many cases, no heat
sink is required. Optimized for use with standard series of inductors available from several different
manufacturers, the TL2575HV-33 and TL2575HV-05 greatly simplify the design of switch-mode power supplies
by requiring a minimal addition of only four to six external components for operation.
The TL2575HV-33 and TL2575HV-05 are characterized for operation over the virtual junction temperature range
of –40°C to 125°C.
