What are the key features of TL2575HV-33IKTTR?
- Fixed 3.3 V output with ±4% accuracy over line, load, and temperature
- Wide 4.75 V to 60 V input voltage range handles high-voltage industrial rails
- Integrated 1 A switch at 52 kHz switching frequency reduces external BOM
What is TL2575HV-33IKTTR used for?
The TL2575HV-33IKTTR is ideal for industrial power supplies operating from 24 V or 48 V bus rails where a regulated 3.3 V output is needed for microcontrollers and logic. It suits telecommunications equipment and automotive accessories requiring robust step-down regulation from elevated supply voltages. The device also fits battery-powered instruments where high input voltage capability and low quiescent current are priorities.

Frequently Asked Questions
What is the maximum input voltage the TL2575HV-33IKTTR can handle?
The TL2575HV-33IKTTR supports an input voltage range of 4.75 V to 60 V, making it suitable for 12 V, 24 V, and 48 V industrial supply rails while delivering a regulated 3.3 V output at up to 1 A.
How does the 52 kHz switching frequency affect inductor selection for TL2575HV-33IKTTR designs?
At 52 kHz, the TL2575HV-33IKTTR typically requires an inductor in the 100 µH to 680 µH range, balancing core losses and ripple current. Lower frequency means a larger inductor compared to 300 kHz–1 MHz controllers, but reduces switching losses and EMI filtering requirements.
Is TL2575HV-33IKTTR a suitable replacement for LM2575HV-3.3 in existing board designs?
The TL2575HV-33IKTTR is functionally equivalent to the LM2575HV-3.3 with the same 3.3 V fixed output, 1 A current limit, and 60 V input rating. Both use a 5-pin package and identical external components, so the TL2575HV-33IKTTR is a drop-in alternative without layout changes.
What output capacitor value is recommended for stable 3.3 V regulation with TL2575HV-33IKTTR?
Texas Instruments recommends an output capacitor of 220 µF to 1000 µF with an ESR below 0.5 Ω for the TL2575HV-33IKTTR. This ensures stability within the control loop and limits output voltage ripple to under 50 mV under typical 1 A load conditions.
