The TPS6131x family is an integrated solution with a wide feature set for driving up to three LEDs for still-camera flash strobe and video-camera lighting applications. It is based on a high efficiency synchronous boost topology with combinable current sinks to drive up to three white LEDs in parallel. The 2-MHz switching frequency allows the use of small and low-profile 2.2-µH inductors. To optimize overall efficiency, the device operates with a low LED-feedback voltage and regulated output-voltage adaptation.

The device integrates a control scheme that automatically optimizes the LED current flash budget as a function of the battery voltage condition.

The TPS6131x not only operates as a regulated current source, but also as a standard voltage boost regulator. The device enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range. These operating modes can be useful to supply other high power devices in the system (for example, a hands-free audio PA).

To simplify video light and flash synchronization with the camera module, the device offers a dedicated control interface (STRB0, STRB1) for zero latency LED turnon time.
