Descripción general

Description

The L4971D is an automotive-grade buck (step-down) switching regulator IC from STMicroelectronics. It’s designed to convert a wide automotive DC input into a stable lower rail for microcontrollers and peripherals in vehicles and harsh-environment electronics. Key features typically include: adjustable output via an external feedback network, current-mode PWM control, soft-start, enable input, overcurrent/short-circuit protection, undervoltage lockout, and thermal protection. It requires external passive components (inductor, input/output capacitors, and a diode or a synchronous stage) to form the regulator. Applications include automotive ECUs, infotainment, dashboards, and other power rails in cars and rugged equipment. For exact specifications (pinout, switching frequency, voltage ranges, packaging), consult the L4971D datasheet and application notes.

Package

L4971D comes in a Multiwatt-7 power package (7-pin with a heatsinking tab).

Pinout

- Pin count: 8 pins (D8/SO8 package)
- Function: Automotive-grade buck switching regulator with integrated high-side MOSFET. Converts high input voltage (up to ~40 V) to a lower output using external feedback, with current‑mode control and protections (enable, soft‑start, overcurrent, thermal/UVLO).

Manufacturer

- Manufacturer: STMicroelectronics (ST).
- What kind of company: A multinational electronics and semiconductor company, headquartered in Geneva, Switzerland, and one of the world's largest semiconductor manufacturers with operations worldwide.

Application

Applications:
- Automotive DC-DC converters (12/24 V input) for ECUs, infotainment and instrument clusters
- Industrial and telecom power supplies needing compact, efficient step-down regulation
- On-board regulators for consumer electronics and battery-powered devices (3.3/5 V rails)
- General-purpose embedded systems requiring reliable switching regulation
