Description

LMR14020SQDPRRQ1 is a Texas Instruments buck (step-down) regulator in the LMR14020 family. It’s designed to convert a higher input voltage into a stable, lower output for point‑of‑load power in automotive and industrial systems. The device integrates the control circuitry and a high-side switch; external components (inductor, output/input capacitors, a catch diode or, in a synchronous variant, a second switch, and a feedback network) set the output voltage. Key features typically include a wide input range, enable/shutdown, protection (undervoltage, thermal, current limit), and high efficiency in a compact surface‑mount package. The SQDPRRQ1 suffix denotes the exact packaging/reel option used for procurement. Common applications are automotive ECUs, industrial controllers, and telecom equipment. For precise electrical specs (Vin range, Vout options, switching frequency, efficiency, pinout, and package details), consult the TI datasheet and product page.

Features

Key features of LMR14020SQDPRRQ1:
- 2-A step-down regulator (Simple Switcher)
- Wide input range: 4.5 V to 42 V
- Adjustable output via external feedback (0.8 V reference)
- High efficiency (up to ~95% depending on conditions)
- Auto PWM/PFM operation for good light-load efficiency
- Enable pin with undervoltage lockout
- Protection: current limit/short-circuit protection and thermal shutdown
- Soft-start to minimize inrush
- Compact SQDPRRQ1 package (QFN with exposed pad) for good thermal performance
Ideal for automotive and industrial power conversion applications.

Package

QFN-8 package (3×3 mm) with exposed pad (MSOP-like small outline face with an exposed thermal pad).

Pinout

Pin count: 8 pins (8-pin package, e.g., VSSOP-8/QFN-8).
Function: 2-A buck (step-down) switching regulator. Key pins typically include VIN, SW (switch node), GND, FB (feedback), EN (enable), and BOOT (bootstrap for the high-side gate drive); the remaining pins are usually no-connects or test pins depending on the exact package variant.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits (ICs) and other semiconductor products; headquartered in Dallas, Texas.
