说明

The TPS61093 is a 1.2-MHz, fixed-frequency boost converter designed for high integration and high reliability. The IC integrates a 20-V power switch, input/output isolation switch, and power diode. When the output current exceeds the over load limit, the IC’s isolation switch opens up to disconnect the output from the input. This protects the IC and the input supply. The isolation switch also disconnects the output from the input during shutdown to minimize leakage current. When the IC is shutdown, the output capacitor is discharged to a low voltage level by internal diodes. Other protection features include 1.1-A peak over-current protection (OCP) at each cycle, output over voltage protection (OVP), thermal shutdown, and under voltage lockout (UVLO).
