Technical Details & Description

What the L6986ITR does on the board

The L6986ITR is a step-down (buck) switching regulator from STMicroelectronics, delivering an adjustable output from a 4 V to 38 V input rail. It uses a synchronous rectifier topology, so the internal low-side FET replaces the external catch diode — that means higher efficiency at low output voltages and a smaller BOM count on the board.

Key parametrics for the design-in decision

Switching frequency is programmable from 275 kHz to 2.2 MHz — the upper end shrinks the inductor footprint, but the trade-off is higher switching losses. Operating junction temperature range is -40°C to +150°C — that is the full industrial and automotive temperature envelope.

Mounting is surface-mount only. The listed packaging options are Tape & Reel (TR) and Cut Tape (CT) — the reel quantity is the standard production format; cut tape is for prototype or low-volume builds.

Frequently asked questions

Where can I buy L6986ITR and how do I get a price?

The L6986ITR is sourced through independent distribution.

What is the L6986ITR's input and output voltage range?

Input voltage range is 4 V to 38 V. Output is adjustable from 0.85 V up to 38 V (the same as the input maximum).
