The AAT2856INJ-EE-T1 from Skyworks Solutions is a highly integrated charge pump with dual linear regulators, optimized for systems powered by lithium-ion/polymer batteries. This device is designed to provide power for white LED backlights, capable of driving up to six LEDs at up to 30mA each.
Key electrical specifications include an input voltage range of 2.7V to 5.5V and a switching frequency of 2MHz for the charge pump. The two integrated linear regulators each offer up to 200mA of output current with a low dropout voltage of 200mV. The output voltage is adjustable from 1.2V to V_BATTERY.
This component features built-in short-circuit and over-temperature protection, along with automatic soft-start circuitry to prevent excessive inrush current. It operates within an ambient temperature range of -40°C to +85°C and is available in a 28-lead TQFN package suitable for surface mounting.
Applications for the AAT2856INJ-EE-T1 include camera-enabled mobile devices, digital still cameras, and multimedia mobile phones where efficient LED backlight control and stable power regulation are required.
