Product Introduction
The TPS6108x is a 1.2 MHz/600 kHz fixed-frequency boost regulator designed for high integration, which integrates a power switch, an I/O 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 0.5 A/1.3 A peak-to-peak overcurrent 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 5 V, such as USB output. The output can be boosted up to 27 V. TPS6108x can provide the supply voltages of OLED, TFT-LCD bias, 12-V and 24-V power rails. The output of TPS6108x can also be configured as a current source to power up to seven WLEDs in flash light applications.
