概述

Description

TPS53127RGER is a TI buck (step-down) switching regulator from the SIMPLE SWITCHER family. It converts a higher input voltage to a lower, regulated output to power digital logic and microcontrollers.
Key points
- Input range and topology: a small, efficient switching regulator; uses external feedback to set output.
- Output: adjustable via resistor divider (typical use is a lower, logic-level rail); designed for portable/embedded power rails.
- Protections and features: enable/soft-start, current limit, overcurrent protection, and thermal shutdown for robustness.
- Package: 8-pin VSSOP-style package; RGER suffix indicates RoHS-compliant, Pb-free, tape-and-reel packaging.
- Applications: power supplies for microprocessors, FPGAs/SoCs, sensors, and other mixed-signal devices in consumer and embedded systems.
Notes
- For exact electrical specs (input range, output voltage options, switching frequency, quiescent current) and typical application circuits, consult the TI TPS53127RGER datasheet and product page.

Features

TPS53127RGER features (concise):
- Dual high-side load switches with built-in current limit
- Enable control for outputs (turn-on/turn-off)
- Undervoltage lockout (UVLO) and thermal shutdown
- Overcurrent/short-circuit protection
- Reverse current protection and output discharge on shutdown
- Slew-rate controlled soft-start to limit inrush
- Small, RoHS-compliant package suitable for Tape-and-Reel (RGER)
Notes: This device is intended for power-distribution in 1–5 V systems, providing compact dual-channel switching with protection and simple control.

Package

VSON-8 (3×3 mm) package, RoHS/lead‑free (TPS53127RGER).

Pinout

- Pin count: 20 pins (VQFN-20/MSOP-20 style package)
- Function: Dual synchronous buck regulator (two-channel step-down DC-DC converter) with integrated high-side/low-side MOSFETs, adjustable outputs via external feedback resistors, and enable control.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs, manufactures, and sells analog and embedded processing integrated circuits and related electronics products.

Application

- Point-of-load DC-DC regulator for CPUs, GPUs, FPGAs, ASICs, and memory
- Power supplies for servers, telecom, and networking equipment
- Embedded systems and industrial automation
- Consumer electronics needing compact, efficient power rails
- Any system requiring a high-efficiency buck regulator from higher input voltages
