GENERAL DESCRIPTION
The ADP3207A1 is a high efficiency, multiphase, synchronous, buck-switching regulator controller optimized for converting notebook battery voltage into the core supply voltage required by high performance Intel processors.
FEATURES
1-, 2-, or 3-phase operation at up to 750 kHz per phase
±8 mV worst-case differential sensing error over
temperature
Interleaved PWM outputs for driving external high power
MOSFET drivers
Enhanced PWM Flex Mode™ for excellent load transient
performance
Automatic power-saving modes maximize efficiency during
light load and deeper sleep operation
Soft transient control reduces inrush current and audio noise
Active current balancing between output phases
Independent current limit and load line setting inputs for
additional design flexibility
Built-in, power-good masking supports VID on-the-fly
7-bit digitally programmable 0.3 V to 1.5 V output
Overload and short-circuit protection with programmable
latch-off delay
Built-in, clock enable output delays CPU clock until CPU
supply voltage stabilizes
Power monitor output signals the total output power of the
buck converter
APPLICATIONS
Notebook power supplies for next generation Intel® processors
