Atmel announces a power management standard product dedicated to the power supplies of handset add-on modules. These modules require a specific regulated power supply interface from the main supply. Manufactured using the company’s mainstream CMOS process, the AT73C211 is designed to supply the digital, analog, interface and, if required, the Radio Frequency (RF) and backup sections of add-on modules used in hand-held products such as PDAs and mobile phones. The AT73C211 integrates a high-performance DC/DC converter with integrated switches to supply digital cores at 1.9 V, delivering up to 300 mA. Additionally, three high-current Low Drop Out (LDO) linear voltage regulators supply analog, interface and RF portions of typical multimedia or wireless communication applications, with voltage from 2.7 to 2.8 V and current up to 130 mA.
