TL3845DR-8 Overview
It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Cut Tape (CT) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 7.6V~30V voltage are supplied and operated. Suitable for working in an dc switcher that has a 0°C~70°C TA. There is a switch at 100kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Connected to a SWITCHING REGULATOR analog IC, the switch converters are connected to a power supply. A switching converters's terminal (s) sits at the DUAL position. 8 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. In addition to "TL3845", there are other relevant dc to dc converter ics you can find. There are only 8 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 30V. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 48 % during power-up and power-down. A frequency of 500kHz is set for the switching controller. There are several dc to dc voltage regulator in the Automotive, AEC-Q100 series. The dc switching utilizes 11mA when it is in a dormant state. For nominal working status, the input voltage can be set as 5.5V. Switching controller is necessary to provide a voltage of 15V. It is important that the controller is supplied with 30mA more than 30mA volts of current.

Aztec Electronics's Payment Terms
Aztec Electronics offers many types of payment options, and support in multiple currencies such as GBP, US dollars, RMB, Rubles, 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, SF Express.
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.
2. If you need a test report, please let us know. We have a long-term cooperative testing laboratory. If you have familiar testing laboratory, we can also ship to your designated laboratory for testing.

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.
