SC8903A is a synchronous 4-switch buck-boost converter with four integrated switches. It is able to effectively output voltage no matter it is higher, lower or equal to the input voltage.SC8903A supports very wide input and output voltage range. It can support applications from 2.7V to 22V input range and 2.7V to 22V output range. It employs current-mode control and supports input current limit, output current limit, dynamic output voltage adjustment, internal current limit and over temperature protections to ensure safety under different abnormal conditions. The SC8903A is in a 40 pin 6x6 QFN package.
