LMR14206XMK: 4.5V to 42V, 0.6A, Step-Down DC/DC Switching Regulator

Product Details:

Model: LMR14206XMK

Package: SOT-23-6

Type: SIMPLE SWITCHER Buck Regulator

Overview:

The LMR14206XMK is a PWM DC/DC buck (step-down) regulator. Its wide input voltage range from 4.5V to 42V makes it suitable for various applications, such as power conditioning from unregulated sources. The LMR14206XMK employs an internal switch with low RDSON (typically 0.9Ω) to achieve maximum efficiency (typically 85%). The fixed operating frequency of 1.25 MHz permits the use of small external components while maintaining low output voltage ripple. Soft-start is implemented via the shutdown pin and an external RC circuit, allowing users to customise the soft-start time for specific applications.

LMR14206XMK Product Features:

Input voltage range: 4.5V to 42V

Output voltage range: 0.765V to 34V

Output current up to 0.6A

1.25 MHz switching frequency

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
