The LM2733 from Texas Instruments is a current-mode boost converter designed for high power density in space-constrained applications. It integrates a 40-V DMOS FET switch capable of handling up to 1 A peak current (1.5-A typ limit) and offers two switching frequency options: 1.6 MHz (X option) for smaller external components or 600 kHz (Y option) for higher efficiency. The device operates over an input voltage range of 2.7 V to 14 V and can generate output voltages up to 40 V. Key features include cycle-by-cycle current limiting, internal compensation, and a logic-level shutdown pin that reduces quiescent current to less than 1 μA. The LM2733 is available in a 5-pin SOT-23 package, making it suitable for portable electronics such as digital cameras, PDAs, white LED backlights, and local boost regulators. Its -40°C to 125°C operating temperature range allows use in industrial and automotive environments.
