General Description

The AS3675 is a highly-integrated CMOS Power and Lighting Management Unit for mobile telephones, and other 1-cell Li+ or 3-cell NiMH powered devices.

The AS3675 incorporates one Step Up DC/DC Converter for white backlight LEDs, one high-power Charge Pump, one Analog-to-Digital Converter, 13 current sinks, the RGB and white LEDs can be controlled by an audio input, LED in-circuit function test, a two wire serial interface, and control logic all onto a single device.

Output voltages and output currents are fully programmable.

Key Features

  • High-Efficiency Step Up DC/DC Converter - Up to 16V/55mA (or 25V/35mA) for White LEDs - Programmable Output Voltage with External Resis- tors and Serial Interface - Over voltage Protection High-Efficiency High-Power Charge Pump - 1:1, 1:1.5, and 1:2 Mode - Automatic Up Switching (can be disabled and 1:2 mode can be blocked) - Output Current up to 300mA/500mA pulsed - Efficiency up to 95% - Very Low effective Resistance (2.5Ω typ. in 1:1.5) - Only 4 External Capacitors Required: 2 x 1µF Flying Ca.
