In portable battery-operated equipment including tablets and smartphones, the display supply and backlight must guarantee the highest possible efficiency and low noise as well as small size and weight.

We have a complete portfolio of linear and switching LED drivers for a wide range of low-voltage battery-operated applications and supporting all topologies including boost, buck and buck-boost. We have a range of dedicated supply solutions for active-matrix organic light-emitting diode (AMOLED) displays.
