Is the inductor getting warm? Boost regulator current draw seems excessive Ask Question.
Price Rohs Orders from Analog Devices. See the examples in the IC’s datasheet. Temperature Range This is the acceptable operating range 2108s the device. Models for the following parts are available in LTspice: The manufacturer of the chip was quite elusive but I was able to identify them.
The model has been scheduled for obsolescence, but may still be purchased for a limited time.
25Pcs 2108A ME2108A50PG ME2108A30PG SOT89
The total solution requires only three tiny external components. The various ranges specified are as follows: You are commenting using your Facebook account.
The ADP is available in fixed output voltages of 3. At least one model within this product family is in production and available for purchase. We have a professional logistics team and a professional logistics information platform, so we can deliver products safe and quickly. The device will function with load voltages smaller than this but output current regulation will be impaired.
Most orders ship within 48 hours of this date. Product Categories Power Management. This is because the ratio of switching time to on time stays constant. New Original BV 2. Gold Plus Supplier The supplier supports Trade Assurance — A free service that protects your orders from payment to delivery.
The multimeter showed a nice, steady 3. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors. To find out more, including how to control cookies, see here: Once an order has been placed, Analog Devices, Inc. The product is appropriate for new designs but newer alternatives may exist.
The CE module fueled by the 1. Email required Address never 21008a public. Thanks much for the info. The Sample button will be displayed if a model is available for web samples. If a model is not available for web samples, look for notes on lc product page that indicate how to request samples or Contact ADI.
With the 1,mAh battery fully charged this circuit could run a theoretical maximum of 28 hours before exhaustion. Seeing a good steady 3. As the film noir approximately said “Forget it, Jake.

To ensure the longest battery life in portable applications, the ADP has a power save mode that reduces the switching frequency under light load conditions.
In a boost converter the input current should be continuous so minimal filtering is required. All versions include an internal power switch and synchronous rect-ifier for minimal external part count and high efficiency. The second graph on page 8 of the datasheet suggests that for an output current of 70mA and an input voltage of 2. Info on these iv modules was hardly available.
Sample availability may be better than production availability.
