Description

The AT73C211 is a power management device for digital, analog, interface, and, in

some cases, RF and backup sections of add-on modules used as accessories in pop-

ular handheld devices like mobile phones, digital still cameras, PDAs and a wide

range of multimedia devices. The AT73C211 can also be used to supply the CPU with

a high-efficiency DC-DC Converter, a radio frequency transceiver with high PSRR and

noise performance LDO regulators, or memories and analog sections with indepen-

dent LDO channels.

In addition, the AT73C211 integrates LDO regulators to recharge backup elements

and convert its voltage to microcontroller RTC supply.

LDO regulators and DC-DC converters output voltage can be programmed by a mask

change.
