3 Description
The LMR14030-Q1 is a 40 V, 3.5 A step down regulator with an integrated high-side MOSFET. With a wide input range from 4 V to 40 V, it’s suitable for various applications from industrial to automotive for power conditioning from unregulated sources. An extended family is available in 2 A and 5 A options in pin-to-pin compatible packages, including LMR14020- Q1 and LMR14050-Q1. The regulator’s quiescent current is 40 µA in Sleep-mode, which is suitable for battery powered systems. An ultra-low 1 μA current in shutdown mode can further prolong battery life. A wide adjustable switching frequency range allows either efficiency or external component size to be optimized. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes the external components of the device. A precision enable input allows simplification of regulator control and system power sequencing. The device also has built-in protection features such as cycle-by-cycle current limit, thermal sensing and shutdown due to excessive power dissipation, and output overvoltage protection. The LMR14030-Q1 is available in an 8-pin HSOIC or 10-pin WSON package with exposed pad for low thermal resistance.

FAQ:
Q: How does Perceptive guarantee that MF10CN is the original manufacturer or agent of MAX?
We have a professional business development department to strictly test and verify the qualifications of MAX original manufacturers and agents. All MAX suppliers must pass the qualification review before they can publish their MF10CN devices; we pay more attention to the channels and quality of MF10CN products than any other customer. We strictly implement supplier audits, so you can purchase with confidence.
Q: How to find the detailed information of MF10CN chips? Including MAX original factory information, Active Filter application, MF10CN pictures?
You can use Perceptive's intelligent search engine, or filter by Active Filter category, or find it through MAX brand manufacturer page.
Q: Are the MAX's MF10CN price and stock displayed on the platform accurate?
The MAX's inventory fluctuates greatly and cannot be updated in time, it will be updated periodically within 24 hours. After submitting an order for MF10CN, it is recommended to confirm the order with Perceptive salesperson or online customer service before payment.
Q: What forms of payment can I use in Perceptive?

Once your order has been processed for shipment, our sales will send you an e-mail advising you of the shipping status and tracking number.
Note: It may take up to 24 hours before carriers will display tracking information. In normal conditions, Express delivery needs 3-5 days, Registered Mail needs 25-60 days.
Q: What is the process for returns or replacement of MF10CN?
All goods will implement Pre-Shipment Inspection (PSI), selected at random from all batches of your order to do a systematic inspection before arranging the shipment. If there is something wrong with the MF10CN we delivered, we will accept the replacement or return of the MF10CN only when all of the below conditions are fulfilled:
(1)Such as a deficiency in quantity, delivery of wrong items, and apparent external defects (breakage and rust, etc.), and we acknowledge such problems.
(2)We are informed of the defect described above within 90 days after the delivery of MF10CN.
(3)The MF10CN is unused and only in the original unpacked packaging.
Two processes to return the products:
(1)Inform us within 90 days
(2)Obtain Requesting Return Authorizations
