The AAP109A and AAP109B are low input voltage boost controllers with two outputs. The output voltages are independently set. The unique aspect of the AAP109A and AAP109B are that the user only needs to provide one boost inductor. The chip contains an internal switching FET and two synchronous rectifiers as well as the needed feedback and control circuitry.
Features
- Input voltage range: 1.5V – 3.5V
- AAP109A: Critical Conduction Mode, Variable Frequency Version
- AAP109B: Fixed Frequency Version
