New Chip Integrates 3 Power Channels and Two Backup Channels for Up to 30 Percent PCB Space and Cost Savings
Add-on modules are a key factor in the marketing strategy of handset manufacturers. Mobile phones, music players, digital still cameras, PDAs and multimedia devices can add GSM/GPRS, 3G, WLAN, Bluetooth(R), GPS, image capture, music playback and other features by simply adding plug-in modules to existing devices. These modules require a specific regulated power supply interface from the main supply.
Manufactured using Atmel's low-cost 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 to DC converter with integrated switches to supply digital cores at 1.9V, delivering up to 300mA. Additionally, three high-current Low Drop Out (LDO) linear voltage regulators supply analog, interface andRF portions of typical multimedia or wireless communication applications, with voltage from 2.7 to 2.8V and current up to 130 mA. An ultra low-power LDO and a back-up battery or supercap charger are also provided to supply the Real Time Clock (RTC) section that is usually present inside the application processor core. This achieves the lowest current consumption possible in standby mode. A reset generator and a voltage supervision function complete the integration of the AT73C211.
"Our AT73C211 is a first in its market," said Michele Casetta, Marketing Manager for Atmel's Power Management and Audio Analog Companion PMAAC(TM) Product Line. "The integration of various power supply channels and an ultra- low-power backup supply channel with a power controller circuit for startup and shutdown, it makes it an ideal companion for every application where power consumption, cost and space are key."
Atmel offers the AT73C211 in a 5 x 5 mm, 25-ball ultra-thin BGA package in order to satisfy portable device manufacturers' minimum space requirements. It is available now mounted on a reference design board or as engineering samples. Production quantities are also available, with a reference price below $1.00 in large quantities.
