Key Features
- Fixed 15 V output voltage-mode switching regulator with 1 A output current capability for easy-to-implement step-down designs
- Wide input voltage range of 4.75 V to 40 V supports diverse 12 V, 24 V, and 36 V bus power architectures
- 5-pin TO-263 surface-mount package with excellent thermal dissipation for continuous 1 A load in compact PCB designs
Applications
TL2575-15IKTTR is used in industrial control panels, test equipment, and consumer electronics to regulate a 24 V or 36 V DC bus down to a fixed 15 V rail for analog signal conditioning and gate-driver supply circuits. Its 52 kHz fixed-frequency switching operation requires only a minimal external BOM of an inductor, diode, and capacitors, simplifying design and reducing time-to-market. The TO-263 package's exposed pad allows direct board-level heat sinking, enabling continuous full-load operation in enclosed enclosures.

Frequently Asked Questions
What input voltage range and output voltage does TL2575-15IKTTR support?
TL2575-15IKTTR accepts an input voltage from 4.75 V to 40 V and produces a fixed 15 V output. It operates at a nominal 30 V input in many industrial designs. The 40 V maximum rating gives headroom for transients on 24 V or 36 V bus systems, and the under-voltage lockout prevents malfunction below 4.75 V input.
How much output current can TL2575-15IKTTR deliver continuously, and what external components does it need?
TL2575-15IKTTR delivers up to 1 A of continuous output current with a typical efficiency of 77% at full load from a 30 V input. The required external bill of materials is minimal: a 100 µH to 220 µH inductor, a Schottky rectifier diode rated at 1 A and 40 V, and input/output decoupling capacitors of 100 µF each. No compensation network is needed due to the internal voltage-mode control loop.
For what applications is TL2575-15IKTTR a better choice than a linear regulator when stepping from 24 V to 15 V?
TL2575-15IKTTR is preferred over a linear regulator when stepping 24 V down to 15 V because the 9 V dropout at 1 A would dissipate 9 W in a linear device, requiring a large heatsink. The switching regulator's approximate 77% efficiency reduces power loss to around 2.7 W, cutting thermal management cost and enabling compact PCB designs in enclosed industrial enclosures without forced-air cooling.
What package does TL2575-15IKTTR use, and how does its thermal performance compare to through-hole alternatives?
TL2575-15IKTTR uses a 5-pin TO-263 (JESD-30 code R-PSSO-G5) surface-mount package with a large thermal pad soldered directly to the PCB copper pour. This provides a junction-to-board thermal resistance of approximately 10°C/W to 15°C/W with adequate copper area, compared to the TO-220 through-hole equivalent which requires a separate external heatsink. The SMT package simplifies automated assembly and suits single-sided board production.
