GENERAL DESCRIPTION
In source mode, the output voltage VVBUS is 5V, 7V, 9V, 12V, 15V, 20V selectable. In sink mode, the output voltage VBAT is adjustable with an external resistor divider. The four integrated low RDS(ON) switches minimize the conduction loss. The SY21612 integrates an I2C compatible interface for mode selecting, output voltage setting, frequency setting, protection setting, and etc. The device is available in compact QFN4×4-32 package.APPLICATIONS
