Catalyst programmable LED driver provides 32 power for camera flash

Announced the analog and mixed signal semiconductor supplier Catalyst Semiconductor, further expanded its product line to launch LED driver, 300mA camera flash LED driver CAT3612 fully programmable. CAT3612 uses the latest EZDim Catalyst design, with a high power channel to meet the needs of flash brightness. The device has compact appearance, providing a space saving 3 x 3mm TDFN package.

According to reports, CAT3612 effectively reduce the complexity of the system, the use of micro controller, through the Catalyst EZDim programming interface, can be programmed to achieve all flash features, including start / turn off and flash brightness adjustment.

When controlling the flash current and brightness, the designer can have 32 programmable output power levels for setting the camera and video mode. While the traditional flash LED device provides only a very limited set and a predefined brightness standard. CAT3612 can maximize battery life, with a power efficiency of 90%. When the battery is not used, the device into the "zero" current interrupt mode to eliminate battery consumption, so as to avoid short-circuit and overload damage.

The device has a low bit of 0.8mm, designed to be compatible with the RoHS 3 x 3mm TDFN package, fixed high frequency (1MHz) operation, effectively reducing the footprint of the system board. CAT3612 can provide RoHS standard products, comply with environmental standards of the green 3mm x 3mm TDFN 12 pin package. Bulk orders for more than 10000 of the unit price of $1.06, you can provide samples and evaluation tools, orders 6 to 8 weeks after arrival.
