Description

TPS53219RGTR is a Texas Instruments DC-DC buck regulator in the SIMPLE SWITCHER family. It integrates the high‑side switch and control circuitry to efficiently step down a higher input voltage to a lower, regulated output for point‑of‑load power in portable and embedded systems. The RGTR suffix indicates RoHS-compliant, Tape‑and‑Reel packaging. A few external components are required: an inductor, input and output capacitors, and a feedback network to set the output voltage. Key features typically include enable/soft‑start, protection (overcurrent, thermal shutdown, and UVLO/OVLO), and a wide input range suitable for battery or other varying sources. The device is commonly used for microprocessor cores, memory rails, FPGA/ASIC power rails, and other compact, efficient power solutions. For exact electrical specs, programming options, and recommended layouts, consult the TI datasheet and design guides.

Features

TPS53219RGTR features (highlights):
- 1-channel buck DC-DC converter with integrated high-side switch
- Wide input range: 2.5 V to 5.5 V
- Output: adjustable via external feedback resistors (fixed-output variants available)
- Fixed-frequency PWM control for stable regulation
- High efficiency power conversion
- Enable (EN) with undervoltage lockout
- Power-good (PG) signal
- Protection: overcurrent/short-circuit, overtemperature, UVLO
- Soft-start and output discharge
- Small RGTR 8-pin package (RoHS compliant)
Note: exact options (e.g., fixed vs. adjustable output, switching frequency) may vary by variant; consult the datasheet for precise specs.

Package

HTSSOP-16 (16-pin thin-shrink SOP) package, RoHS/green lead-free, with Tape & Reel packaging.

Pinout

- Pin count: 8 pins
- Function: It is an 8-pin buck (step-down) DC-DC switching regulator. It accepts input (VIN), provides a regulated output via an external inductor, and requires feedback (FB) and enable (EN) control. The device includes a switch/LX pin (switch node) and ground, plus the necessary supply pins to operate the regulator.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures integrated circuits, specializing in analog, mixed-signal, and embedded processing products. It is one of the world's largest semiconductor producers.

Application

TPS53219RGTR is a high-efficiency synchronous buck regulator suitable for point-of-load power in many systems. Typical applications include:
- CPUs/GPUs/SoCs, memory, and programmable logic rails
- Telecom and networking equipment
- Servers and data-center infrastructure
- Industrial automation and robotics
- Automotive instrumentation
- Portable/embedded consumer electronics
It provides compact, efficient DC-DC conversion for multiple rails from a higher input supply.
