LM2665M6/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LM2665M6/NOPB is a monolithic, high-voltage, high-efficiency synchronous step-down converter housed in a compact 6-pin SOT-23-6 package. Specifically designed for applications requiring a regulated output voltage from a wide input voltage range of 4.5V to 28V, it boasts a switching frequency of 1.2MHz, minimizing external component size. The device integrates a high-side MOSFET and a low-side synchronous MOSFET, achieving efficiencies exceeding 90% at typical operating conditions. Its internal 1.2A peak current capability allows for relatively high power delivery in space-constrained designs. _x000D_

The LM2665M6/NOPB features adjustable output voltage via an external resistor divider, offering design flexibility. Protection features include cycle-by-cycle current limiting and thermal shutdown, enhancing system robustness. Common use cases include powering portable devices, battery-powered equipment, and industrial control systems requiring a regulated low-voltage rail from a higher-voltage source. Its small size, high efficiency, and integrated protection mechanisms make it a superior choice compared to discrete solutions or less integrated converters, particularly where board space and power consumption are critical design parameters. The “NOPB” suffix denotes lead-free packaging, compliant with RoHS directives.
