High Efficiency, Synchronous, Buck-Boost Converter with Four Integrated MOSFET
PQ8726A
PQ8726A 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. PQ8726A supports very wide input and output voltage range. It can support applications from 2.7V to 22V input range and 2.4V 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. PQ8721 employs current-mode control and supports output current limit, dynamic output voltage adjustment, internal current limit, output short protection and over temperature protections to ensure safety under different abnormal conditions. The IC is in a 21 pin 4x4 QFN package.
