General DescriptionLBut
The LM2841 and LM2842 are PWM DC/DC buck (step-down) regulators. With a wide
input range from 4.5V-42V, they are suitable for a wide range of applications
such as power conditioning from unregulated sources. They feature a low RDSON
(0.9Ω typical) internal switch for maximum efficiency (85% typical). Operating
frequency is fixed at 550 kHz (X version) and 1.25 MHz (Y version) allowing
the use of small external components while still being able to have low output
voltage ripple. Soft-start can be implemented using the shutdown pin with an
external RC circuit allowing the user to tailor the soft-start time to a
specific application.
The LM2842 is optimized for up to 600 mA load currents while the LM2841 is
optimized for up to 300 mA load current. Both have a 0.765V nominal feedback
voltage.
Additional features include: thermal shutdown, VIN under-voltage lockout, and
gate drive under-voltage lockout. The LM2841 and LM2842 are available in a low
profile TSOT-6L package.
