Key Features
- Fixed 12V output voltage-mode step-down regulator with integrated switch, oscillator, and comparator — reduces BOM to just inductor, diode, and capacitors
- Wide 4.75V–40V input voltage range handles automotive, industrial, and telecom rail variations without derating
- 52kHz fixed switching frequency with 1A continuous output current enables compact magnetics and low-ripple designs
Applications
The TL2575-12IKV is widely used in industrial power supplies and embedded systems requiring a stable 12V rail from higher-voltage bus inputs such as 24V or 28V. It suits point-of-load conversion in telecom equipment, motor drive control boards, and programmable logic controller (PLC) power stages. Its low external component count makes it ideal for cost-sensitive designs where board space and assembly complexity must be minimized.

Frequently Asked Questions
What is the input voltage range of the TL2575-12IKV?
The TL2575-12IKV accepts an input voltage from 4.75V minimum to 40V maximum, with a nominal rating of 25V. This wide range makes it suitable for 12V, 24V, and 28V bus applications in industrial and automotive environments.
How much output current can the TL2575-12IKV deliver?
The TL2575-12IKV delivers up to 1A continuous output current at a fixed 12V regulated output. This is sufficient for powering logic boards, sensors, relay coils, and low-power actuators commonly found in embedded and industrial systems.
What package does the TL2575-12IKV come in and what are its thermal characteristics?
The TL2575-12IKV is housed in a 5-pin TO-263 surface-mount package with JEDEC code R-PZFM-T5. The TO-263 package provides enhanced thermal dissipation compared to through-hole equivalents and is fully compatible with standard reflow soldering for high-volume PCB assembly.
Is the TL2575-12IKV RoHS and lead-free compliant?
Yes. The TL2575-12IKV carries JESD-609 code e3 and a confirmed Pb-free designation, meaning it meets RoHS lead-free requirements. It is acceptable for use in environmentally regulated products sold in the EU, China RoHS, and similar markets globally.
What are common applications for the TL2575-12IKV?
The TL2575-12IKV is commonly used in step-down DC-DC conversion for industrial control systems, telecom infrastructure boards, PLC power stages, and embedded computing modules. Its integrated oscillator, comparator, and switch reduce external component count to just an inductor, catch diode, and output capacitor, simplifying layout and reducing assembly cost.
