700mA High Power White LED Driver With Standard Logic Interface

The TPS6105x device uses a high-frequency synchronous-boost topology with constant current sink to drive single white LEDs The device uses an inductive fixed-frequency PWM control scheme using small external components, minimizing input ripple current.
The 2-MHz switching frequency allows the use of small and low-profile 2.2-H inductors. To optimize overall efficiency, the device operates with only a 250-mV LED feedback voltage.
The TPS6105x device not only operates as a regulated current source, but also as a standard voltage-boost Regulator This additional operating mode CAN be useful to supply other high-power devices in the system, such as a hands-free Audio Power Amplifier or any other component requiring a supply voltage higher than the battery voltage.
The LED current or the desired output voltage CAN be programmed via two Logic signals (MODE0/1). To simplify Flash synchronization with the camera module, the device offers a trigger pin (FLASH_SYNC) for fast LED turn-on time.
When the TPS6105x is not in use, it CAN be put into shutdown mode, reducing the input current to 0.3 A (typ). During shutdown, the LED pin is high impedance to avoid leakage current through the LED
