TPS6108x Integrated Switch & Power Diodes

Texas Instruments TPS6108x Integrated Switch & Power Diodes feature a 1.2MHz/600kHz fixed-frequency boost regulator designed for high integration. The device combines a power switch, an I/O isolation switch, and a power diode. The isolation switch opens up to disconnect the output from the input when a short-circuit condition is detected. This feature results in the IC and input source protection from being shorted to ground, except V_IN. Leakage current is prevented when the isolation switch disconnects the output from the input during a shutdown. Additional protection features include 0.5A/1.3A peak-to-peak overcurrent protection, programmable soft-start (SS), over-voltage protection (OVP), thermal shutdown, and under-voltage lockout (UVLO). The device is powered by a single Li-ion battery, triple NiMH, and regulated 5V, such as USB output. The Texas Instruments TPS6108x provides the supply voltages of OLED, TFT-LCD bias, 12V, and 24V power rails. The output can be boosted up to 27V, and can also be configured as a current source to power up to seven WLEDs in flashlight applications.
