SC8751 is a synchronous 4-switch buck-boost converter with an I2C interface. It provides excellent power efficiency and voltage regulation no matter the output voltage is higher, lower, or equal to the input voltage.The device is specially designed for a single Li-ion battery powered system. It can support applications from 2.7V to 5.5V input range and 3V to 5.2 V output range. It also features low quiescent current and selectable PSM mode operation to maximum efficiency at light load. The MODE bit allows the user to choose between power-save-mode operation and forced PWM operation. During the shutdown, the load is discontented from the input, and the fast discharge function actives to discharge the output capacitors rapidly.The device features an I2C interface, so the user can easily control the output voltage and other control functions. The I2C address can be selected through an ADDR pin with options from 0X75H or 0X76H. SC8751 employs peak current-mode control and supports cycle-by-cycle current limit, input under-voltage protection, output short protection, and over-temperature protection to ensure safety under different abnormal conditions. SC8751 is in a 15-ball 2.135 x 1.365 WCSP package.
