NON-ISOLATED LED LIGHTING DRIVE IC WITH HIGH PFC AND HIGH
CONSTANT CURRENT ACCURACY
DESCRIPTION
SD6900 is designed for non-isolated LED driving with floating
Buck structure. With this structure, inductor current will be
sensed and closed-loop is formed with the internal error
amplifier for high constant current accuracy and high
input/output regulation rate. Also, high PF in full range is
available as its own PFC control. Boundary Conduction mode is
adopted for decreasing switching loss and improving the
conversion efficiency.
SD6900 integrates various protections, such as output open
circuit protection, output short circuit protection, cycle-by-cycle
current limit protection, over temperature protection and VCC
over voltage protection.
The start-up current and operating current are low and highlight APPLICATION
LED can be driven with high efficiency in full range
(85VAC~265VAC).
FEATURES
* Bulb Lamp
* T5/T8 LED Lamp
* Various LED Lighting
* Proprietary constant control method (Patent)
* Constant current with high accuracy for LED (<±3%)
* PF>0.9 in full voltage range
* High efficiency >93% (18W)
* Boundary-Conduction mode
* LED short circuit protection (Patent)
* LED open circuit protection
* VCC over/under voltage protection
* Over temperature protection
* Over current protection
