GENERAL DESCRIPTION

The ADP3210 is a high efficiency, multiphase, synchronous, buck-switching regulator controller optimized for converting notebook battery voltage into the core supply voltage of high performance Intel processors. The part uses an internal 7-bit DAC to read voltage identification (VID) code directly from the processor that sets the output voltage. The phase relationship of the output signals can be configured for 1-, 2-, or 3-phase operation, with interleaved switching.

FEATURES

1-, 2-, or 3-phase operation at up to 1 MHz per phase

Input Voltage Range of 3.3 V to 22 V

±8 mV worst-case differential sensing error over temperature

Interleaved PWM outputs for driving external high power MOSFET drivers

Automatic power-saving modes maximize efficiency during light load and deeper sleep operation

Active current balancing between output phases

Independent current limit and load line setting inputs for additional design flexibility

7-bit digitally programmable 0 V to 1.5 V output

Overload and short-circuit protection with latch-off delay

Built-in clock enable output for delaying CPU clock synchronization until CPU supply voltage stabilizes

Output Current Monitor

APPLICATIONS

Notebook power supplies for next generation Intel® processors
