austriamicrosystems Develops AS3603 PMU

austriamicrosystems AG (Graz, Austria) unveiled the AS3603, an enhanced version of its AS3601 power management unit (PMU) platform. Providing mobile device manufacturers with a versatile power management IC, this integrated real-time programmable power management IC delivers price/performance characteristics, consuming 60% less PCB space and costing 50% less than comparable solutions.

The AS3603 features a highly efficient, dc-dc down-converter and ultra-low power LDOs, all programmable in 0.05V steps, to ensure operating time. The AS3603's feature set also includes a highly efficient driver for white LEDs and a programmable 1W audio amplifier suitable for hands-free mobile phone applications – all on a single chip. Mono to differential conversion of the audio signal, which has been integrated into the AS3603, delivers high power output for the hands-free function while eliminating the need for costly, space-consuming external components.

The AS3603 is available in a QFN48, 6mm x 6mm, 0.4mm pitch packaging or QFN48, 7mm x 7mm, 0.5mm pitch packaging, and is priced at approximately $1.70 in high-volume production quantities.
