DC-DC Step-Up Boost Regulator, 1.6MHz, 2A, SOT-23-5

The DC-DC Step-Up Boost Regulator from Texas Instruments is a high-performance switching regulator designed to deliver reliable power conversion for a wide range of applications, including LCD displays, embedded systems, and consumer electronics. Operating at a fixed frequency of 1.6MHz, this current-mode boost converter ensures efficient performance with minimal power loss, thanks to its internal 1.4A switch. Its capability to achieve greater than 90% duty cycle makes it ideal for boosting input voltages from as low as 2.7V up to 14V to output voltages ranging from 3V to 20V, supporting a maximum output current of 2A.

The regulator features a logic-level shutdown pin that reduces quiescent current to less than 1µA, significantly extending battery life in portable devices. Protection is provided through cycle-by-cycle current limiting and thermal shutdown, ensuring safe operation under adverse conditions. Internal compensation simplifies design, reducing external component count and making this regulator extremely easy to integrate into your projects.

This product is a green solution, free from antimony and bromine, and comes in a compact SOT-23-5 package, suitable for surface-mount applications. Its wide operating temperature range from -40°C to 125°C ensures reliable performance in demanding environments. Whether you are developing power management systems, embedded designs, or consumer electronics, this boost converter delivers the efficiency and reliability you need.
