The MAX8760 evaluation kit (EV kit) demonstrates the high-power,
dynamically adjustable multiphase notebook CPU
application circuit. This DC-DC converter steps down high-voltage
batteries and/or AC adapters, generating a precision,
low-voltage CPU core VCC rail. The MAX8760 EV kit
meets the mobile AMD K8 and K8 Rev F VID code set and
CPU transient voltage specifications. The MAX8760 EV kit
consists of the MAX8760 dual-phase Quick-PWM™ step-down
controller and the MAX6509 temperature sensor.
The MAX8760 EV kit includes active voltage positioning
with adjustable gain, reducing power dissipation and bulk
output capacitance requirements. Precision slew-rate control provides "just-in-time" arrival at the new DAC setting, minimizing surge currents to and from the battery.
This fully assembled and tested PC board provides a 6-bit
digitally adjustable output voltage from a 7V to 24V battery
input range. The EV kit operates at 300kHz switching frequency
and has superior line- and load-transient response.
