Datasheet

LM2733XMF/NOPB – 1A, 40V High-Frequency Boost Switching Regulator IC

The LM2733XMF/NOPB is a compact, high-efficiency current-mode boost DC-DC converter designed to provide powerful performance in space-constrained applications. Operating at a fixed frequency of 1.6MHz, this “X” version enables the use of small inductors and capacitors, reducing board space while maintaining excellent power conversion efficiency. Featuring an internal 40V, 1A switch, the LM2733XMF/NOPB delivers outstanding power density and is ideal for designs requiring boosted output voltages of 16V or higher.

The device’s SOT-23-5 package and minimal external component requirements make it perfect for compact, high-performance power designs such as portable electronics, sensor modules, and communication systems. The logic-level shutdown pin enables ultra-low quiescent current, extending battery life in energy-sensitive applications. Built-in cycle-by-cycle current limiting and thermal shutdown protection ensure reliable operation even under overload or fault conditions. Internal compensation simplifies circuit design, making the LM2733XMF/NOPB a cost-effective and easy-to-implement high-frequency boost solution.
