Description:
SR1582 is a high-efficiency linear constant-current driver chip, its simplified circuit architecture makes it easy to most LED products.
The internal of SR1582 integrates with Power MOSFET, output current can be set up to 80mA by using external resistance. If a greater output current is needed,
Chips connect in parallel mode can achieve such current. SR1582 has over temperature protection and compensation function. when surface temperature of the chip rises to 110℃, it will linearly reduces the output current on the basis of temperature. This feature can avoid the flicker problems caused by traditional over temperature protection methods.
