DC Switching Voltage Regulators

TPS62046DGQ Description

The TPS62046DGQ from Texas Instruments is a high-efficiency, synchronous step-down (buck) DC-DC converter designed to deliver a fixed 3.3V output with a 1.2A continuous output current. Operating over a 2.5V to 6V input voltage range, it is optimized for battery-powered and low-voltage applications. The device integrates synchronous rectification, enhancing efficiency and reducing external component count. With a 1.25MHz switching frequency, it enables compact designs by allowing the use of smaller inductors and capacitors. Packaged in a 10-pin HVSSOP, it is suitable for space-constrained applications and complies with ROHS3 and REACH environmental standards.

TPS62046DGQ Features

• High Efficiency: Synchronous rectification achieves up to 95% efficiency, minimizing power loss.
• Wide Input Range: Supports 2.5V–6V, making it ideal for single-cell Li-ion, 3.3V/5V rails, and battery-powered systems.
• Compact Design: 1.25MHz fixed frequency operation reduces PCB footprint with tiny passive components.
• Low Quiescent Current: Optimized for battery longevity in portable devices.
• Robust Protection: Includes thermal shutdown and overcurrent protection for reliable operation.
• MSL1 (Unlimited): Suitable for extended storage and handling in manufacturing.
