The LM2840, LM2841 and LM2842 are PWM DC/DC buck(step-down) regulators. With a wide input range from4.5V-42V, they are suitable for a wide range of applicationssuch as power conditioning from unregulated sources. Theyfeature a low RDSON (0.9Ω typical) internal switch for maxi-mum efficiency (85% typical). Operating frequency is fixed at550 kHz (X version) and 1.25 MHz (Y version) allowing theuse of small external components while still being able to havelow output voltage ripple. Soft-start can be implemented usingthe shutdown pin with an external RC circuit allowing the userto tailor the soft-start time to a specific application.The LM2840 is optimized for up to 100 mA, the LM2841 for300 mA and the LM2842 is optimized for up to 600 mA loadcurrents. They all have a 0.765V nominal feedback voltage.Additional features include: thermal shutdown, VIN under-volt-age lockout, and gate drive under-voltage lockout. TheLM2840, LM2841 and LM2842 are available in a low profileTSOT-6L package
