Overview of LM2842YMK-ADJL/NOPB
The LM284x SIMPLE SWITCHER™ devices are PWM DC/DC buck (step-down) regulators. With an input range from 4.5 V to 42 V, they are suitable for a wide range of applications, such as power conditioning from unregulated sources. They feature a low RDSON (0.9‑Ω typical) internal switch for maximum efficiency (85% typical). Operating frequency is fixed at 550 kHz (X option) and 1.25 MHz (Y option), 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 (SHDN) pin with an external RC circuit allowing the user to tailor the soft-start time to a specific application.
The LM2840 is optimized for up to 100 mA, the LM2841 for up to 300 mA, and the LM2842 for up to 600‑mA load currents. They all have a 0.765-V nominal feedback voltage.
Additional features include: thermal shutdown, VIN undervoltage lockout, and gate-drive undervoltage lockout. The LM284x are available in a low-profile SOT-6L package.
