UC3842AD8 Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 10V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for work in a 0°C~70°C TA dc switcher. A switching controller such as this can switch at a value of Up to 500kHz . The Surface Mount makes it ideal for general dc dc regulator. The dcdc regulator features Frequency Control for efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 8 terminations can be used for a wide range of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics can be found by searching "UC3842". There are only 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 5V voltage according to the test statistics. You should note down the dc dc regulator's usual output current of 1A when you start a project. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. Switching controllers operate at 450kHz frequencies. A nominal working status is achieved when the input voltage is set to 15V. The maximum input voltage of the dc switcher is 25V, so users need to limit the voltage accordingly. Switching controller is necessary to provide a voltage of 11V. The dc switcher will not provide an output current greater than 1A. 25mA more than 25mA current should be supplied to the controller. If the current flow input is 11mA, the switching converter could operate.

Aztec Electronics's Payment Terms
Aztec Electronics offers many types of payment options, and support in multiple currencies such as GBP, US dollars, RMB, etc. As relationships are built, payment plans can be established so that payments can be made on a predetermined time frame after receipt of the invoice.
T/T IN ADVANCE (Pay at time of order placement via wire transfer)
How to Ship Electronic Components?
We take great care when shipping electronics overseas. Both the U.S. and U.K. governments have imposed restrictions on air transport of electronics, according to the International Air Transport Association.
1. Understand the shipping rules of the destination country
Different countries have different regulations for shipping electronic equipment, check for certain certifications, and read the destination country's guidelines before shipping to prevent delays or confiscation of goods by customs.
2. Choose a reliable express logistics provider
From providing pick-up service to checking the status with real-time order number, conveniently track packages. At present, the logistics providers we cooperate with more include DHL, UPS, Fedex, TXT.
Of course, if you have a long-term cooperative freight forwarder or your own company's logistics account, you can pick up the goods directly from our warehouse
3. How much does it cost to ship the electronic components?
The shipping cost of electronic products depends on the size and weight of the package and the shipping distance. You can first ask us about the size/weight of the products we sell to estimate the shipping cost.
4. How long does it take to ship the electronic components?
If electronic component in stock, it is usually shipped before 5 o'clock on the same day, and it usually takes 5-10 working days to complete it by international express.
If it is a scheduled component, it needs to wait for the arrival of the parts, and then it will be inspected before delivery. If there are special circumstances, the sales staff will confirm with you. Weekends and holidays will also affect the delivery time of electronic products.
1. We provide 365 days warranty for all electronic components.

After the electronic components have passed the quality inspection of Aztec Electronics, there are generally the following five packaging forms for electronic components: Tape, Tube, Tray, Bulk and Ammo.
Tape/Reel | Tube | Tray | Bulk | Ammo |
Weave bulk chips into tapes and pack them into reels through SMD components packaging Tape Machine. Reel is the most commonly used. | When packaging, arrange the components in the same direction and put them into plastic tubes one at a time. | Choose tray package with the same specifications as the original manufacturer, put the components into the tray and use the strapping machine. | Bulk packaging means that the SMD components are freely packaged in a formed plastic box or bag. | Adhesive tape cut continuously in predetermined quantities. The cut strips are placed in boxes for safekeeping. |
Choose electronic components that are vacuum-sealed against water, dust, moisture, oxidation, corrosion, and even UV or RF pollution.
