Silan launched high power green lighting LED driver

Hangzhou Silan microelectronics company recently launched a green lighting LED series of high performance, high reliability, high power drive solutions and the core chip, which is applied to MR16 lamp SD42522 and SD42525, SD42524 used in landscape lighting, street lamp and daylight lamp used in SD42528, GU10 and E27 used in high pressure the SD6856 lamp. The chip uses a Silan designed for high performance green energy products developed by BCD technology, part of products using the patented techniques Silan, widely used in MR16 lamp, high-pressure lamp, landscape lighting, LED lamps and LED fluorescent lamps and other LED lighting field.

SD42522/24/25 is a 6~36V input, 1A high power LED driver IC, the use of advanced system architecture, built in resistance 0.4 to 0.5 ohm LDMOS tube, high system efficiency. SD42522/24 uses average current control mode, the output current accuracy can reach + 1.5%; SD42525 using hysteresis control mode, the output current compensation circuit built-in patented technology Silan, less peripheral elements, without loop compensation. SD42528 is a 6~60V input, high power LED current to 1A driver chip, with the average current mode control LDMOS power switch, built-in pressure tubes 80V, open circuit protection and short circuit protection function built-in Silan patent technology, and makes the LED circuit in the abnormal state will not be large current impact. The series of chips are integrated with temperature protection, current limiting protection circuit.

In addition, Silan also launched for primary LED drive control switching power supply SD6856, MOS chip external drive tube, output power is 5~7W, can provide accurate constant current control loop (CV/CC), has a very high stability and average efficiency. Later, Silan will launch a primary control mode with LED SCR dimmer and PFC drive control chip SD6858.
