Catalyst launches low-noise LED drive

Analog and mixed signal semiconductor supplier Catalyst Semiconductor company to further expand its product line to launch the CAT3614 LED driver; 3mm x 3mm compact package, with the 1 line interface of EZDim low noise LED driver. For portable backlight applications, the CAT3614 can be driven up to 5.5V4 2.5V white LED channels. 1 times /1.5 times fractional pump and up to 91% power efficiency. "Zero" current shutdown mode to soft start with current limit to eliminate battery consumption, so as to avoid short circuit and overload damage.

Chip start, turn off and LED dimming are each using a new 1 line digital interface to complete. This single serial interface eliminates the need for a pulse width regulator or a multi line control method, and the LED current can be accurately controlled at every 1 mA level 32. CAT3614 current regulation method reduces flicker and eliminates noise by eliminating LED current setting resistors.

Compatible with RoHS 3 x 3mm dual flat leadless TDFN package design, fixed high frequency operation, effectively reducing the system board occupied. CAT3614 can provide RoHS standard products, environmentally friendly green halogen free and lead packaging. Bulk orders for more than 10000 unit price of $0.94, can provide samples and evaluation tools.
