概述

Description

L7986TR is STMicroelectronics’ L7986 family DC-DC switching regulator in Tape & Reel packaging. It’s a monolithic power-management IC that integrates the control logic and a high‑side power switch to convert input voltage to a stable output. The device is used to build efficient buck/boost regulators for automotive and general power-supply applications, depending on the variant. Features typically include protection (overcurrent/short‑circuit, thermal shutdown, undervoltage lockout) and, in some configurations, input/output sequencing. External components (inductor, diode or synchronous rectifier, and feedback network) are required to set the output voltage and operating mode. Exact specs (input range, output voltage, switching frequency) vary by variant; refer to the L7986TR datasheet for precise values and packaging details.

Package

TR means Tape‑and‑Reel packaging. L7986TR is the L7986 device shipped in reel form; the actual package body is the standard power package used by L7986 variants (see the datasheet for exact package type, e.g., TO‑220 or D²PAK).

Pinout

- Pin count: 8 pins (8-pin package, TR = Tape & Reel)
- Function: High-efficiency buck (step-down) switching regulator with integrated high-side MOSFET (automotive power regulator). Requires external feedback resistors (and inductor) to set output; includes features such as enable, soft-start, and current-limit protection.

Manufacturer

- Manufacturer: STMicroelectronics (ST)
- Kind of company: A global multinational semiconductor company that designs, manufactures, and markets integrated circuits and discrete semiconductors for automotive, industrial, consumer, and communications markets. Headquartered in Geneva, Switzerland.

Application

L7986TR is used in these application areas:
- Automotive DC-DC converters (car electronics, infotainment)
- Industrial power supplies
- LED driver circuits and backlighting
- Battery-powered portable devices requiring high-efficiency step-down regulation
