STMicroelectronics STCF02
The STCF02 is a high efficiency power supply solution to drive a single flash LED in camera phone, PDAs and other hand-held devices. It is a buck-boost converter that guarantees a proper LED current control over the battery voltage (particularly in the case, when the output voltage is lower than the input voltage); the output current control ensures a good current regulation over the forward voltage spread characteristics of the Flash LED. This highly efficient converter is able to accept input current from the battery (lower than 1.5A), while limiting the peak inductor current to 2.3A (typ).| Part No. | STCF02 |

DESCRIPTION
Three logic input signals can select 5 modes of operation: Shutdown mode (quiescent current less than 1µA typ), Shutdown mode with NTC active, Torch mode (drives the LED up to 250mA), Flash mode (up to 600mA), and Medium flash mode (reduces the flash current). Other features include Soft start control, thermal shutdown, short circuit protection, overvoltage protection, and LED temperature protection. An alternative to LED temperature protection is that a safety flash time-out feature can be implemented instead. This device is available in a QFN20, 4mm x 4mm, no-lead package (height is less than 1mm).●
