概要

Description

TPS54061QDRBTQ1 is a Texas Instruments buck DC-DC converter (Simple Switcher) designed to efficiently step down a higher input voltage to a lower regulated output. It integrates the power switches and PWM control logic in a compact package for high-efficiency power conversion.
Key points:
- Wide input voltage range suitable for automotive/industrial use
- Adjustable output via external resistor divider
- Enable/shutdown control, soft-start
- Protection features: overcurrent/short-circuit protection, thermal shutdown, undervoltage lockout
- Designed for high efficiency in compact designs
- QDRB suffix indicates a RoHS-compliant lead-free QFN package with exposed pad
Applications include automotive, industrial, and battery-powered systems. For exact electrical specs (input range, output voltage options, current capability, and required external components), consult the TPS54061 datasheet.

Features

TPS54061QDRBTQ1 Features (highlights)
- Automotive-grade (AEC-Q100 Grade 1) device
- Wide input range: 4.5 V to 60 V
- 6 A continuous output current (high‑current buck regulator)
- External feedback for adjustable output (0.8 V to ~6 V range; using resistor divider)
- Internal high‑side switch with current‑mode control
- High efficiency (typical) and small solution size
- Enable (EN) input with undervoltage lockout
- Protections: cycle‑by‑cycle current limit, overcurrent/short‑circuit protection, thermal shutdown, and input fault protection
- Integrated soft‑start to limit inrush
- Suitable for automotive/industrial applications; available in QFN packaging (QDRB/TQ1 variants)
Note: Exact output voltage options (fixed vs. adjustable) and switching frequency are specified in the datasheet for your specific variant.

Package

An 8-pin VQFN package (3×3 mm).

Pinout

- Pin count: 16 pins (QFN/DRB package)
- Function: Automotive-grade buck DC-DC switching regulator (step-down) with an integrated high-side switch; requires external inductor, diode (or uses one path depending on variant), and input/output capacitors. Provides adjustable output via feedback, plus enable, soft-start, and protection features (overcurrent/thermal).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is a multinational American semiconductor company that designs and manufactures a broad range of analog, embedded processing, and related ICs for automotive, industrial, consumer electronics, and communications markets.
