                      SC8721B
                      High Efficiency, Synchronous, Buck Boost Converter with Four Integrated MOSFET
                      Introduce
                       

                      SC8721B 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. SC8721B supports very wide input and output voltage range. It can support applications from 2.7V to 22V input range and 0.7V to 22V output range. Through its I2C interface, user can program the output voltage and output current limit and switching frequency. VINREG voltage can be adjusted by external resistor. SC8721B employs current-mode control and supports output current limit and dynamic output voltage adjustment for different application conditions. The IC is in a 21 pin 4x4 QFN package.
