Additional Infomation About Product

STCF03 High power white LED driver with IC interface Features Buck-boost DC-DC converter Drives one power white LED up to 800 mA from 2.7 V to 5.5 V in QFN Drives one power white LED up to 800 mA from 3.3 V to 5.5 V in BGA Efficient up to 92% QFN20 (4 x 4) TFBGA25 (3 x 3) Output current control 1.8 MHz typ. fixed frequency PWM Packages: Synchronous rectification QFN20 (4 x 4) Full IC control TFBGA25 (3 x 3) Operational modes: Shutdown mode Applications Shutdown + NTC Ready mode + auxiliary red LED Cell phone and smart phone Flash mode: up to 800 mA Camera flashes/strobe Torch mode: up to 200 mA PDAs and digital still cameras Soft and hard triggering of flash Flash and torch dimming with 16 exponential Description values The STCF03 is a high efficiency power supply Dimmable red LED indicator auxiliary output solution to drive a single flash LED in camera Internally or externally timed flash operation phone, PDAs and other hand-held devices. It is a buck - boost converter to guarantee a proper LED Digitally programmable safety time-out in flash current control over all possible conditions of mode battery voltage and output voltage the output LED overtemperature detection and protection current control ensure a good current regulation with external NTC resistor over the forward voltage spread characteristics of Opened and shorted LED failure detection and the flash LED. Thanks to the high efficiency of the protection converter allows having the input current taken from the battery remain under 1.5 A. Chip over temperature detection and protection < 1 A shutdown current Table 1.
