Datasheet Brief KTD2694 For full datasheet, click HERE. 2MHz, 1.5A Flash LED Driver with Low-Vin Protection in UDFN Features Brief Description Drive up to 1.5A flash current KTD2694 is the ideal power solution for high-power flash Programmable threshold low-voltage input LEDs used with cell phone camera modules or digital still protection cameras. It is a highly integrated step up DC-DC converter High efficiency converter (up to 90%) with very high switching frequency, fixed at 2MHz, Input voltage range: 2.7V to 5.5V providing a very small total solution for portable photo 2MHz step-up converter flash. KTD2694 uses ExpressWire single-wire Very small inductor: 1.0H to 2.2H programming for maximum flexibility. The maximum flash- Very small load capacitor: 4.7F to 10F mode LED current is set by an external resistor, and the TM ExpressWire digital control enables and flash-mode and movie-mode currents can be programmed programs flash and movie current in 16 steps in 16 steps by the ExpressWire interface at CTRL pin. An External resistor sets maximum flash current AUX pin allows highest priority ON/OFF flash mode Integrated thermal regulation control control. KTD2694 internally monitors the input voltage, 2mA LED shorting test current and 1.7V disabling LED current when the supply drops below the forward voltage threshold programmed threshold voltage. LED open/short protection The LED output sink can drive up to 1.5A continuous LED Over-voltage protection current. Thermal regulation is integrated in flash mode to Cycle-by-cycle inductor current limit limit the ICs temperature and continuously provide the Programmable Flash Timeout protection 0.1A maximum allowed output current. shutdown current Pb-free Package: UDFN22-10L Various protection features are built into KTD2694, -40C to +85C Temperature Range including cycle-by-cycle input current limit protection, output over-voltage protection, LED fault (open or short) Applications protection, flash timeout protection and thermal shutdown protection. The leakage current in shutdown mode is Mobile Phones 0.1A. Smart Phones and PDAs KTD2694 is available in a RoHS and Green compliant Digital Still Cameras 10-lead 2mm x 2mm x 0.52mm UDFN package.
