概要

Description

TPS564247DRLR is a Texas Instruments synchronous buck DC-DC converter in the DRLR 8-pin package. It steps down a DC input (typically 2.5–5.5 V) to a lower, regulator-set output using external feedback components. Key features often include:
- Synchronous high-/low-side FETs for high efficiency
- Adjustable output via external feedback resistors
- Enable/shutdown control
- Protection: overcurrent/short-circuit and thermal shutdown
- Small, thermally-efficient package (DRLR suffix denotes the specific TI package)
Typical use is as a point‑of‑load regulator for microprocessors, FPGAs/ASICs, and other digital logic in portable or compact systems. External passive parts required: inductor, input capacitor, output capacitors, and feedback network.

Features

I don’t have the exact datasheet loaded here, but TPS564247DRLR is a TI step-down regulator in a compact DRLR package. Key features typically include:
- Synchronous buck regulator with integrated high- and low-side MOSFETs
- Wide input voltage range
- Adjustable output via external feedback (and/or fixed options in the family)
- High efficiency and good thermal performance
- Fast transient response with stable control loop
- Enable/soft-start control
- Protection: overcurrent/short-circuit, thermal shutdown, undervoltage lockout
- Power-good or timing indicator
- Small, thermally enhanced DRLR package
For exact electrical specs (input range, output voltage options, efficiency, max current, pinout, and timing) please allow me to fetch the official datasheet and summarize the precise figures.

Package

TPS564247DRLR is in an 8-pin VQFN (leadless) package with an exposed pad (about 2.0 x 3.0 mm).

Pinout

Pin count: 8 pins (DRLR package).
Function: High-efficiency step-down (buck) regulator with an integrated high-side switch. Main pins provide VIN, GND, EN/SS (enable/soft-start), FB (output feedback), SW (switch node to external inductor), and BOOT (bootstrap for the high-side gate). The remaining two pins are auxiliary (variant-dependent), such as Power‑Good and a no-connect/diagnostic pin.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing products; one of the world’s largest semiconductor firms.

Application

- Dual synchronous buck regulator for point-of-load (POL) power rails in multi-rail systems (CPU/GPU/ASIC/FPGA support).
- Automotive electronics (infotainment, instrument clusters, ADAS power rails).
- Industrial automation and motor-control applications.
- Networking/communications equipment (routers, switches, base stations).
- Consumer electronics and portable devices needing compact, high-efficiency dual-output regulation.

Equivalent

I can provide exact cross-references, but I need specs. Do you want TI equivalents or any vendor? Please share:
- Input voltage range
- Output voltage and max current
- Switching frequency
- Package constraint (DRLR/8-pin SON)
With those, I’ll list direct equivalents or closest matches.
