SGM3134 Description
The SGM3134 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. It is optimized for low power keypad and portable backlighting applications. The SGM3134 uses an internal resistor to set the bias current for four LEDs, which are matched to ±5%.
SGM3134 Key Features
- Support up to 4 LEDs
- Low 40mV Dropout at 20mA
- Less than ±5% LED Current Matching
- Simple LED Brightness Control
SGM3134 Applications
- Support up to 4 LEDs
