The AAT2848IDG-T1 from Skyworks Solutions is a high-current charge pump designed for backlight and flash applications in devices like camera-enabled mobile phones and digital still cameras.
This device integrates four backlight LED current sinks, each capable of driving up to 30mA, and two flash LED current sinks, each capable of driving up to 300mA for a total of 600mA. It operates using a tri-mode charge pump (1x/1.5x/2x) and is optimized for systems powered by lithium-ion/polymer batteries.
Control is managed through an independent I2C serial digital interface, allowing for 32 levels of programmable current for the backlight and 16 levels for the flash. The charge pump includes features such as built-in fade-in/out for backlight control and a programmable safety timer for flash protection. It also incorporates short-circuit and over-temperature protection, along with soft-start circuitry to prevent inrush current.
The AAT2848IDG-T1 is available in a space-saving TQFN33-20 package and operates within an ambient temperature range of -40°C to +85°C.
