Let's start the journey together.
The ams brand, owned by ams AG, the OSRAM brand, owned by OSRAM GmbH, are separately registered trademarks.

The standard backlight and keypad lighting functions are enabled in a flexible way by either a charge pump or an inductive step-up converter. The ICs come with a sophisticated, autonomous pattern generator which produces cool event and fun light patterns. They also support new features such as ambient light sensing and daylight sensing.
Some of the products offer light-to-audio synchronization for use in phones with a media playing capability. The lighting management product portfolio meets the space, feature and cost requirements of all phones from entry-level products up to high-end smartphones.
