概要

Description

TPS566231RQFR is a Texas Instruments buck (step-down) DC-DC converter in the TPS5662x family. It is used to generate a stable, lower-voltage rail from a higher input for digital loads (CPUs, FPGAs, microcontrollers, etc.) in embedded and portable systems. Key features (typical of the TPS5662x family) include enable/shutdown control, soft-start for controlled ramp, fast transient response via current‑mode control, and built‑in protection such as overcurrent/short-circuit protection and thermal shutdown. It also provides a Power-Good signal and options for fixed or adjustable outputs through a feedback network. The RQFR suffix indicates packaging details: RoHS-compliant, lead-free, tape-and-reel, in a QFN-style package. For exact electrical specs (input voltage range, available output voltages, current capability, efficiency) refer to the TPS566231 datasheet and the packaging note for the RQFR variant.

Features

TPS566231RQFR features (highlights):
- Buck DC-DC converter with integrated high-side switch
- Input voltage range: typically 2.7–5.5 V
- Output: adjustable via external resistor divider (0.8 V up to several volts; fixed variants available)
- Fixed-frequency operation around 1 MHz with current-mode control (PWM and light-load modes)
- High efficiency (high-load and light-load efficiency for small form factors)
- Enable (EN) input to shut down the device; Power-Good (PWRGD) output
- Protection: cycle-by-cycle current limit, overtemperature shutdown, and fault hiccup
- Soft-start to limit inrush; fast transient response
- Packaging: 16-pin QFN (RQFR/Tape & Reel) with exposed pad; RoHS-compliant
Note: exact output ranges and switching frequency may vary by variant; consult the datasheet for precise numbers.

Package

QFN-16 (3 × 3 mm) package with an exposed pad (EP); RoHS-compliant.

Pinout

Pin count: 8 pins (in a small 8-pin package such as VSSOP-8/QFN-8).
Function: It's a 1-A buck (step-down) DC-DC converter (SIMPLE SWITCHER) with an internal high-side switch. It accepts VIN, provides a regulated output via an external inductor, and uses FB for output sensing. It also has an EN pin to enable/disable and a GND pin; the remaining pins are the switch node (SW) and typically a return/NC as per package.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital integrated circuits and embedded processing solutions.

Application

TPS566231RQFR is a high‑efficiency 2-A buck regulator used as a point‑of‑load power supply. Applications include powering microprocessors, FPGAs, memory and other digital ICs in motherboards, notebooks, data centers and telecom/network gear; industrial controls and automation; consumer electronics and portable devices.
