The AS3603, an enhanced version of the company’s AS3601 power-management platform, is said to provide mobile device manufacturers with a versatile power-management integrated controller (IC). The platform’s feature set includes an efficient driver for white LEDs and a programmable 1-W audio amplifier, which is said to be ideal for hands-free mobile phone applications—and comes on a single chip. Mono to differential conversion of the audio signal, which has been integrated into the enhanced platform, reportedly delivers high-power output for the hands-free function, while eliminating the need for costly, space-consuming external components.
