New White LED Step-Up Converter from Semtech Integrates Schottky Diode for a Tiny Total Solution
Semtech Corp. has announced the SC4509, the newest product addition to its handheld power management portfolio. The SC4509 is a step-up converter for white LED backlight applications with an integrated Schottky diode in a 2 x 2 x 0.8 mm package.
SC4509 measures only 2mm x 2mm and features efficiency of over 80%
The SC4509 can drive up to five white LEDs in series to provide a tinysolution for small LCD displays. The device’s built-in Schottky diode saves board space and reduces costs while still providing efficiencies of over 80%, which is better than most competitive devices with integrated Schottky and similar to many that require an external Schottky.
