Product details

The TL2575HV-05IKTTR is a step-down buck regulator from Texas Instruments, delivering a fixed 5V output at up to 1A from a 4.75V to 60V input rail. Switching at 52 kHz, the device uses a non-synchronous topology with a positive output configuration, suitable for point-of-load regulation in industrial and automotive environments.

Temperature grade and deployment context

Rated for operation from -40°C to 125°C junction temperature, the TL2575HV-05IKTTR covers the industrial temperature band and extends into under-hood automotive ambient conditions where 105°C is common. The 60V maximum input voltage provides headroom for 12V and 24V systems with load-dump transients, reducing the need for external clamping circuitry in battery-powered applications.

Frequently asked questions

What is the closest functional second-source for TL2575HV-05IKTTR?

The TPS65261RHBT is a different device — a triple-output, adjustable, 2 MHz synchronous buck converter in a smaller package. It is not a pin-compatible or direct functional replacement for the single-output, fixed 5V, 52 kHz non-synchronous TL2575HV-05IKTTR. A board redesign would be required to substitute.
