LM2842XQMK/NOPB

TEXAS INSTRUMENTS  LM2842XQMK/NOPB  直流-直流开关降压逐步递减稳压器, 可调, 4.5V-42V输入, 765mV-34V输出, 0.6A输出, TSOT-23-6

The is a step-down DC-to-DC Regulator suitable for a wide range of applications such as power conditioning from unregulated sources. They feature a low RDSON 0.9R typical internal switch for maximum efficiency 85% typical. Operating frequency is fixed at 1.25MHz 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 600mA load current. They all have a 0.765V nominal feedback voltage. Additional features include thermal shutdown, VIN undervoltage lockout and gate drive undervoltage lockout.
