概述

Description

TPS61073DDCR is a Texas Instruments DC-DC converter in the TPS6107x family. It’s a compact, highly efficient synchronous switching regulator designed for battery-powered portable electronics. It can operate from a wide input range (typical for a single Li‑ion cell up to a few volts) and provides a regulated output to power microcontrollers, sensors, and RF components. The device integrates the control logic and the high- and low-side MOSFETs, delivering high efficiency via synchronous rectification and a fixed switching frequency. Features typically include an enable input, undervoltage lockout, overcurrent protection, thermal shutdown, and overload protection. The DDCR suffix denotes the package type (a small lead-free QFN/DFN package). Typical applications: wearables, handheld devices, and compact power-management designs. For exact electrical characteristics—input range, output voltage options, efficiency curves, pinout, and package dimensions—consult the TI datasheet and product page.

Features

TPS61073DDCR features (concise):
- High-efficiency boost DC-DC converter for battery-powered applications
- Wide input range suitable for single-cell to multi-cell batteries
- Adjustable output via external feedback resistors (FB)
- Fixed-frequency operation enabling small inductors and few external parts
- Integrated switch with minimal external components required
- Enable (EN) input for low-power shutdown
- Soft-start to limit inrush current
- Protection: current limit, overtemperature/thermal shutdown
- Low quiescent current and good light-load efficiency
- Small 6-pin DDCR package for compact designs
Common applications: wearable devices, portable sensors, cameras, and other battery-powered electronics.

Package

TPS61073DDCR is in an 8-pin VSON-8 package (3×3 mm) with an exposed pad (thermal pad) option.

Pinout

- Pin count: 8 pins (VSON-8 package, code DDCR).
- Function: Boost (step-up) DC-DC converter with an integrated switch; converts a lower input voltage to a higher regulated output. Includes VIN, GND, SW (switch node), FB (feedback), EN (enable), and other typical pins in this package.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital integrated circuits, processors, and related solutions; headquartered in Dallas, Texas.

Application

TPS61073DDCR is a high‑efficiency boost regulator for battery‑powered portable electronics. Typical applications: generating higher voltage rails from a single-cell Li‑ion/Li‑poly battery (e.g., 3.3V or 5V) for microcontrollers, memories, and peripherals; powering LED backlights and indicators; USB OTG/adapters; wearables, IoT sensors, and handheld medical/fitness devices.

Equivalent

Closest equivalents are other devices in TI’s TPS6107x family. Drop-in substitutes include: TPS61070, TPS61071, TPS61072, TPS61074, TPS61075, TPS61076, TPS61077, TPS61078, TPS61079. Ensure the same package (DDCR), input/output voltage ranges and current rating; non-TI parts require checking pinout and specs for compatibility.
