TPS6105x 1.2-A High-Power White LED Driver
2-MHz Synchronous Boost Converter WithI2C Compatible Interface Features 3 DescriptionThe TPS6105x deviceis based ona high-frequency Four Operational Modes synchronous-boost topology with constant current– Torch and Flashupto ILED= 1200 mA sinkto drive single white LEDs. The device uses an Voltage-Regulated Boost Converter: 4.5V,5 inductive fixed-frequency PWM control scheme using and 5.25V small external components, minimizing input ripple
current.– Shutdown: 0.3 μA (Typical)
The 2-MHz switching frequency allows the useof• Total Solution Circuit Area<25 mm2
small and low profile 2.2-μH inductors. To optimize• Upto 96% Efficiency overall efficiency, the device operates with onlya•I2 C-Compatible Interfaceupto 400 kbps 250-mV LED feedback voltage. Integrated LED Turnon Safety Timer The TPS6105x device not only operates asa• Zero Latency TX-Masking Input (TPS61050) regulated current source, but also asa standard Hardware Voltage Mode Selection Input voltage-boost regulator. This additional operating
mode can be useful to supply other high-power(TPS61052)
devicesin the system, such asa hands-free audio• Integrated ADCfor LEDVF Monitoring power amplifier,or any other component requiringa• Integrated Low Light Dimming Mode supply voltage higher than the battery voltage (refer LED Disconnect During Shutdown to TPS61052). Open and Shorted LED Protection For highest flexibility, the LED currentor the desired Overtemperature Protection output voltage can be programmed through anI2C
compatible interface. To simplify flash• Availableina 12-Pin NanoFree™ (CSP) and synchronization with the camera module, the device10-Pin QFN Packaging offersa trigger pin (FLASH_SYNC) for fast LED
turnon time.
2 ApplicationsWhen the TPS6105xis notin use,it can be put into• Camera White LED Torch/Flashfor Cell Phones, shutdown mode through theI2 C-compatible interface,Smart-Phones and PDAs reducing the input currentto 0.3 μA (typical). During• Audio Amplifier Power Supply shutdown, the LED pinis high impedanceto avoid
leakage current through the LED.
