TPS62112RSAT  

DC Switching Voltage Regulators

TPS62112RSAT Description

The TPS62112RSAT from Texas Instruments is a high-efficiency, synchronous step-down (buck) DC-DC converter designed for applications requiring a stable 5V fixed output at up to 1.5A of continuous current. With a wide 3.1V to 17V input voltage range, this regulator is ideal for systems powered by batteries, industrial supplies, or automotive sources. The device operates at a 1MHz switching frequency, enabling the use of small external components while minimizing output ripple. Packaged in a compact 16-pin QFN (RSAT), it supports surface-mount assembly and is available in Tape & Reel (TR) for automated production. Compliant with ROHS3 and REACH standards, it meets stringent environmental and safety requirements.

TPS62112RSAT Features

• High Efficiency: Synchronous rectification ensures up to 95% efficiency, reducing power dissipation and thermal stress.
• Wide Input Range: Supports 3.1V–17V, making it versatile for battery-powered and industrial applications.
• Fixed 5V Output: Eliminates the need for external feedback resistors, simplifying design.
• 1MHz Switching Frequency: Enables compact PCB layouts with small inductors and capacitors.
• Low Quiescent Current: Optimized for power-sensitive applications.
• Protections: Includes overcurrent, overtemperature, and undervoltage lockout (UVLO) for robust operation.
• MSL 2 (1 Year): Suitable for extended storage in humid environments.

TPS62112RSAT Applications

• Portable Electronics: Ideal for 5V rails in tablets, handheld devices, and IoT sensors.
• Industrial Systems: Powers PLC modules, sensors, and control circuits with high noise immunity.
• Automotive Subsystems: Suitable for infotainment, ADAS, and telematics due to wide input tolerance.
• Embedded Computing: Provides efficient power for single-board computers (SBCs) and FPGAs.
• Battery-Powered Devices: Extends runtime in medical devices, drones, and wireless nodes.

Conclusion of TPS62112RSAT

The TPS62112RSAT stands out for its high efficiency, compact footprint, and robust performance in demanding environments. Its fixed 5V output, wide input range, and integrated protections make it a superior choice over non-synchronous or adjustable regulators. Whether for portable, industrial, or automotive applications, this regulator delivers reliable power with minimal external components, reducing both cost and design complexity. Texas Instruments’ reputation for quality further ensures long-term supply and support.
