DC484A

DC484A is a demonstration circuit featuring the LT1937 constant current white LED driver in a small SOT23 Thin SOT package. The demo board is designed to demonstrate the high efficiency performance and the small size of the LT1937. The LT1937 features a 95mV feedback voltage, 1.2MHz switching frequency and a special internal compensation network, which allows small (0603) input and output capacitors. DC484 is specifically designed for white LED backlight applications using 2–4 LEDs, making LT1937-SOT23 an ideal solution for battery powered portable applications such as cellular phones, digital cameras, MP3 players, GPS receivers, and handheld computers (PDAs).
