Description

TPS53219RGTR is Texas Instruments’ DC-DC buck regulator in a compact package. It’s designed to step down a higher input voltage to a stable, lower output with high efficiency for point‑of‑load applications. The device typically includes an integrated switching regulator with an internal high‑side switch, current‑mode control, enable/shutdown, soft‑start, and protections (overcurrent/thermal). Output voltage is set via external feedback resistors (or fixed variants, depending on the part). RGTR indicates RoHS-compliant packaging (tape & reel). For exact electrical specs—input voltage range, available output voltages, maximum load current, and switching frequency—refer to the TPS53219 datasheet and TI product page.

Features

TPS53219RGTR is a compact TI buck regulator. Key features include:
- High-efficiency step-down regulator with integrated MOSFETs
- Adjustable output (via external feedback) or fixed-output option
- Wide input voltage range (suitable for various supply rails)
- Enable/shutdown control for power saving
- Internal soft-start and output discharge
- Overcurrent/short-circuit protection and thermal shutdown
- Under/over-voltage protection and protection hysteresis
- Small package (RGTR) suitable for compact boards
- Suitable for automotive/industrial environments (device options vary by grade)
Note: exact voltage ranges, current capability, switching frequency, and protection specifics are defined in the datasheet for TPS53219RGTR.

Pinout

- Pin count: 8 pins
- Function: Monolithic buck (step-down) switching regulator with integrated high-side switch and control logic to regulate a lower output voltage from a higher input, including feedback/enable features.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: Texas Instruments is an American multinational technology company and one of the world's largest semiconductor manufacturers, specializing in analog, mixed-signal, and embedded processing integrated circuits.

Application

TPS53219RGTR is a high‑efficiency synchronous buck regulator ideal for point‑of‑load and VRM applications. Typical use areas:
- CPU/GPU, FPGA/ASIC, and SoC voltage rails in desktops, servers, and embedded systems
- Telecom and networking equipment power distribution and VRMs
- Distributed/POE power architectures and load-switching rails
- Industrial automation, motor drive electronics, and instrumentation
- Data centers, storage systems, and client electronics requiring compact DC‑DC conversion

Package

TPS53219RGTR uses an 8-pin VSON package (2.9 × 3.0 mm), RoHS-compliant, with a Tape & Reel (RGTR) packaging suffix.
