This is the acceptable operating range of the device. Here’s what the ZXLD datasheet has to say about output voltage related to input voltage:. Home Questions Tags Users Unanswered.
power – Boost regulator current draw seems excessive – Electrical Engineering Stack Exchange
You are commenting using your WordPress. ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. 22108a Types Trade Assurance. Temperature Range This is the acceptable operating range of the device.
Price Rohs Orders from Analog Devices. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board. The resulting high VIN ripple may also be causing you to get an erroneous input voltage reading. Sign up or log in Sign up using Google.
It uses a proprietary, high speed current mode, constant frequency PWM control scheme for excellent stability and transient response. Excluding Pin Size 11mm x The product is appropriate for new designs but newer alternatives may exist.
25Pcs 2108A ME2108A50PG ME2108A30PG SOT89
Other key features include undervoltage lockout to prevent deep battery discharge and soft start to prevent input current over-shoot at startup. Info on these tiny modules was hardly available. The regulator should boost the voltage to 3.
The multimeter showed a nice, steady 3. The CE module fueled by the 1. Once an order has been placed, Analog Devices, Inc. My application draws about 75mA when on, and about uA in sleep mode, which would seem to be in-spec. Microsoft Excel download tool from ADIsimPower to generate a power supply design complete with a schematic, bill of materials, and performance specifications.
The specific part is obsolete and no longer available. Pin Count is the number of pins, balls, or pads on the device. If they used a 1N rather than 17 and a crappy cheap inductor that would about explain it. Thanks for the reply. About product and suppliers: Also, please note the warehouse location for the product ordered. However, this doesn’t necessarily explain why you’re also seeing low efficiency in your actual application circuit – unless you are also lacking input decoupling there as well, and your input source isn’t close and low impedance.
Excluding Pin Size 11mm x Notify me of new posts via email. As an idea, what happens if you supply only 1. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. All the IC options come sorted and stored in the kit with the Analog Devices part number clearly printed on each antistatic zip-top bag.
Looks like two ceramic caps in parallel across the output, but nothing at all on the input. See the video posted immediatly below. Transit times from these sites may vary. Model 2108x model number is a specific version of a generic that can be purchased or sampled.
