Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Other Parts Discussed in Thread: LM2623 , LM2621 , LM2665 , TPS60141 , LM2700 Two questions on the LM2623:
System requirements: Input source = 2AA batteries in series. --- Output = 7.5V, 5mA Max.
Q1) I ran through the design calculations and used the on line…
power quick search returns 39 options for charge pumps and dc/dc switching converters. More option if you want a controller w/ external FETs or a module. I would probably go with a converter or charge pump. So it will depend on your other care abouts…
