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. The output can be boosted up to 27V. TPS61080/1 can provide the supply voltages of OLED, TFT-LCD bias, 12V and 24V power rails. The output of TPS61080/1 can also be configured as a current source to power up to 7 WLED in flash light applications.
