Product Summary
The TPS61081DRCR 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 applications of the TPS61081DRCR include 3.3V to 12V, 5V to 12V and 24V Boost Converter, White LED Backlight for Media Form Factor, Display, OLED Power Supply, xDSL Applications, TFT-LCD Bias Supply, White LED Flash Light.
