ADP3209

FEATURES

GENERAL DESCRIPTION

Single-chip solution

Fully compatible with the Intel® GMCH chipset voltage

regulator specifications

Integrated MOSFET drivers

8 mꢀ worst-case differentially sensed core voltage error

over temperature

Automatic power-saving modes maximize efficiency during

light load operation

Soft transient control reduces inrush current and audio noise

Independent current limit and load line setting inputs for

additional design flexibility

The ADP3209 is a highly efficient, single-phase, synchronous

buck switching regulator controller. With its integrated drivers,

the ADP3209 is optimized for converting the notebook battery

voltage to render the supply voltage required by high performance

Intel chipsets. An internal 5-bit DAC is used to read a VID code

directly from the chipset and to set the GMCH core voltage to a

value within the range of 0.4 V to 1.25 V.

The ADP3209 uses a multimode architecture. It provides program-

mable switching frequency that can be optimized for efficiency

depending on the output current requirement. In addition, the

ADP3209 includes a programmable load line slope function to

adjust the output voltage as a function of the load current so that

the core voltage is always optimally positioned for a load transient.

The ADP3209 also provides accurate and reliable current overload

protection and a delayed power-good output. The IC supports

on-the-fly output voltage changes requested by the chipset.

Built-in power-good masking supports

voltage identification (ꢀID) on-the-fly transients

5-bit, digitally programmable DAC with 0.4 ꢀ to 1.25 ꢀ output

Short-circuit protection with programmable latch-off delay

Output power or current monitor options

32-lead LFCSP

APPLICATIONS

Notebook power supplies for next-generation Intel chipsets

The ADP3209 is specified over the extended commercial tempera-

ture range of 0°C to 100°C and is available in a 32-lead LFCSP.
