TPS61080DRCR

TPS61080DRCR Description

The TPS61080DRCR from Texas Instruments is a high-efficiency, adjustable-output DC-DC boost converter designed for applications requiring regulated voltage above the input supply. This obsolete but robust IC operates within an input voltage range of 2.5V to 6V, delivering a maximum output voltage of 27V with a 500mA switch current capability. It supports 600kHz or 1.2MHz switching frequencies, enabling flexibility in design trade-offs between efficiency and component size. Packaged in a 10-VSON (DRC) form factor, it is optimized for surface-mount applications and complies with ROHS3 and REACH environmental standards.

TPS61080DRCR Features

• Wide Input/Output Range: Operates from 2.5V–6V input and delivers 2.5V–27V adjustable output, ideal for battery-powered systems.
• High Switching Frequency: Selectable 600kHz/1.2MHz operation reduces inductor size while maintaining efficiency.
• Non-Synchronous Boost Topology: Simplifies design with an external Schottky diode for cost-sensitive applications.
• Compact Footprint: 10-VSON package (3mm x 3mm) saves PCB space in portable electronics.
• Low Quiescent Current: Enhances battery life in standby modes.
• Robust Protection: Features inherent overcurrent and thermal shutdown protection.

TPS61080DRCR Applications

• Battery-Powered Devices: Ideal for 1-2 cell Li-ion/alkaline/NiMH systems requiring step-up conversion (e.g., portable medical devices, handheld instruments).
• OLED/LCD Bias Supplies: Generates high-voltage rails for display drivers.
• Industrial Sensors: Powers low-voltage sensors from single-cell batteries.
• Wearables & IoT: Compact size and efficiency suit space-constrained designs.

Conclusion of TPS61080DRCR

The TPS61080DRCR excels in compact, efficient boost conversion for low-input-voltage systems, offering design flexibility with adjustable output and dual-frequency operation. While marked obsolete, its performance in battery-driven and portable applications remains relevant for legacy designs or inventory-based projects. Engineers should evaluate alternative TI boost converters (e.g., TPS61099) for new designs requiring modern features like synchronous rectification.
