For LM replacement searchselect a main parameter tolerance value and adjust the checkboxes for feature match. The schematic is simple, easy to build and cost effective, producing dattasheet from a 5V unregulated supply with a maximum output current of mA. The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout.

Farnell element14 UK 3. Chip One Stop The part from Pulse has the following specifications: Features of the Boost Converter are fixed 52 kHz switching frequency, a typical inductor size of The input capacitor C1 should be a good quality, low ESR, 0.

Meet us at the Embedded Show in Nuremberg You can design and make your own inductor using a suitable core recuperated from old equipment if you have the knowledge, practical experience and equipment for this task. The product counter within the button shows the number of available equivalents and a click on the replacement button shows all possible replacements within a parametric overview. But the inductor is one of the most critical components in these types of circuits, so it’s much safer and simpler to or use ready made off-the shelf parts: LM is a Available Distributors with stock: Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM LM Price breaks and distributor sample stock.

If the IC is located far from the supply source filter capacitors, an additional larger electrolytic capacitor e. LM Boost Converter Overview. Available Distributors without stock: The output voltage is given by the following formula:. Fresh Search Replacement Search with. The IC has a wide input voltage range 3. The LM is available in different packages: Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors.

The design uses the adjustable version of LM, but the 12V fixed-voltage version LMT will also work if you remove R1 and R2 and connect datasheett feedback pin directly to the regulator’s output. Link to the most up-to-date LM datasheet and the product page for EVM, tools and support information.
