This is because the ratio of switching time to on time stays constant. If they used a 1N rather than 17 and a crappy cheap inductor that would about explain it. Model The model number is a specific version of a generic that can be purchased or sampled. View Detailed Reference Design Information. You are commenting using your Facebook account. Detect And Zero Rightmost One. Models for the following parts are available in LTspice: We do take orders for items that are not in stock, so delivery may be scheduled at a future date.
Contact For Free Shipping. Product Lifecycle Production At least one model within this product family is in production and available for purchase. The resulting high VIN ripple may also be causing you to get an erroneous input voltage reading. The package for this IC i. Excluding Pins 11mm x The output current of a Boost converter is discontinuous.
Is the inductor getting warm? I added no filtering capacitor — this is with just the module. Looks like your input voltage is close to the output voltage.
Package Description The package for this IC i. Leave a Reply Cancel reply Enter your comment here Pin Count is the number of pins, balls, or pads on the device. The characteristics seem to match, as do the example circuits.
The RedyKit simplifies product evaluation by providing two assembled and tested evaluation boards, plus a full set of product voltage options for an IC regulator. The maximum load current of mA is achievable across the input voltage range.
ME2108A50PG 2108A-5V 3V 3V micro-boost IC components support
Boost regulator current draw seems excessive Ask Question. We will ship all your order within working daysafter receving your payment. Thanks much for the info. We have a professional logistics team and a professional logistics information platform, so we can deliver products safe and quickly. Excluding Pin Size 11mm x In a boost converter the input current should be continuous so minimal filtering is required. Original Electronic Components However, upon connecting everything I found out it was drawing significantly more current than I was expecting, even with the device in sleep mode.

As Iout tends to 0, so does efficiency for all converters I’ve ever seen. ADI’s Design Center lets you design your power circuits in three easy steps. I can be underdimensioned popular for inductors on switching converterscounterfeit, poor quality, or omitted entirely.
The seller does not specify the regulator used.
