8.2 DCDC Step-Down Converter

These converters are meant to convert the battery voltage down to voltages which fit to the core and peripheral supply voltage requirements for

microprocessors.

Input Voltage VSUP1/2/3 (usually connected to VSUPSW)

Output Voltage CVDD1 & CVDD2 & CVDD3

Output voltage levels can be programmed independently form 0.61V to 3.35V

The default value at start-up is defined by the boot ROM

DVM for all three outputs with selectable timings

Driver strength 700mA, DCDC2 & 3 can be combined together to double the output current

Under- and over-voltage detection

High efficiency current force mode

1MHz or 2MHz switching frequency

Fast regulation mode
