概述

Description

TPS62A03DRLR is a Texas Instruments DC-DC buck regulator (step-down converter) in the TPS62A0x family. It is designed to take a higher input voltage and regulate it down to a lower rail for microcontrollers, sensors, and other digital peripherals in compact designs.
Key points:
- High-efficiency step-down regulator suitable for small portable and wearable devices.
- Integrated control logic with enable/shutdown, soft-start, and protection features (e.g., overcurrent/thermal protection).
- Typically supports an adjustable output via external resistors (and/or fixed-output options, depending on variant).
- Requires an external inductor and catch diodes or can be a synchronous design depending on the exact variant.
- DRLR suffix indicates a specific packaging/tape-and-reel option and RoHS-compliant lead-free package.
For exact electrical specs, pinout, soft-start settings, current limits, and application guidance, consult the TPS62A03DRLR datasheet and TI product page.

Features

TPS62A03DRLR is a triple (three-channel) buck regulator in a compact package. Key features include:
- Input range: 1.8 V to 5.5 V
- Three independently regulated outputs (per-channel current ~50 mA; total ~150 mA)
- Outputs adjustable via external resistors (with options for fixed outputs)
- Independent enable for each channel
- Fixed switching frequency with PWM control and internal soft-start
- High efficiency and low quiescent current
- Protection: overcurrent/short-circuit protection, thermal shutdown, undervoltage lockout
- Power-on reset/power-good signaling
- RoHS-compliant, lead-free DRLR package
Note: exact per-channel current and voltage ranges depend on the specific device revision and external resistor settings; consult the datasheet for precise numbers.

Package

TPS62A03DRLR is an 8-pin X2SON (leadless) package, typically 2.0×2.0 mm. The “DRLR” suffix denotes RoHS lead-free and Tape & Reel packaging.

Pinout

- Pin count: 8 pins (8-pin package, e.g., VSON/SOIC variants)
- Function: Fixed-output buck (step-down) DC-DC regulator. It integrates the high-side MOSFET and control circuitry to convert a higher input voltage to a fixed 3.3 V output, with enable (EN) and feedback (FB) pins, plus VIN, GND, and LX/SW pins.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational corporation that designs and manufactures semiconductors and integrated circuits, specializing in analog and embedded processing products.

Application

- Portable and battery-powered devices (handhelds, wearables, IoT sensors)
- Embedded systems needing multiple rails and compact power management
- Automotive and industrial electronics requiring efficient, space-saving buck regulation
