Zywyn recently introduced the ZD832, a universal transformerless AC-DC constant current LED driver for the industrial lighting and display lighting markets.
The device is a high voltage, AC-DC constant current driver for driving a string of white or RGB LEDs in series without the use of an external transformer or bridge rectifier. It operates from a direct input voltage of 85 to 240 V a.c. directly from the AC mains and generates a programmable constant output current of up to 30 mA using a single resistor. This opens up new design and processing methodology in dealing with off-line AC-DC applications in display and lighting.
The ZD832 also features PWM and analogue dimming control with over-temperature protection and over-voltage limiting functions. With high voltage isolation supported by robust proprietary processing technology, there is no EMI generation and it does not require any additional EMI filtering circuits.
