Overview
The LM2733XMF/NOPB is a high-performance boost converter from Texas Instruments, designed to operate as a current-mode boost regulator. It is available in two switching frequency options: 1.6 MHz (‘X’ option) and 600 kHz (‘Y’ option). This device is packaged in a compact 5-pin SOT-23 (DBV) package, which enables high power density due to the minimal power loss of the internal 1-A switch and the use of small inductors and capacitors. The 40-V internal DMOS FET switch makes it ideal for boosting voltages to 16 V or greater. The LM2733XMF/NOPB features a logic-level shutdown pin to reduce quiescent current and extend battery life, along with protection mechanisms such as cycle-by-cycle current limiting and thermal shutdown.
