Description

The TPS61080/1 is a 1.2MHz/600kHz fixed frequency boost regulator designed for high integration, which integrates a power switch, an input/output isolation switch and a power diode. When a short circuit condition is detected, the isolation switch opens up to disconnect the output from the input. As a result, the IC protects itself and the input source from any pin, except VIN, from being shorted to ground. The isolation switch also disconnects the output from input during shutdown to prevent any leakage current. Other provisions for protection include 0.5A/1.3A peak-to-peak over current protection, programmable soft start (SS), over voltage protection (OVP), thermal shutdown and under voltage lockout (UVLO).

The IC operates from input supplies including single Li-ion battery, triple NiMH, and regulated 5V, such as USB output.
