TPS61181 One-Cell Battery Application for Tablet PC Backlight
PDF, 63 Kb, Archivo publicado: sept 9, 2010
The TPS61181 is an ideal LED driver IC for medium form factor LCD backlighting. This device has a built-in, high-efficiency boost regulator with integrated 1.5-A/40-V power MOSFET. It provides six, current-sink regulators of 25 mA. The device can support up to 60 white LEDs. In addition, the boost output automatically adjusts its voltage to total LEDs forward voltage to optimize the whole solution
