Dual-Phase, Quick-PWM Controller for AMD
Mobile Turion 64 CPU Core Power Supplies
General Description
The MAX8760 is a dual-phase, Quick-PWM?, step-
down controller for 6-bit VID AMD Mobile Turion? 64
CPU core supplies. Dual-phase operation reduces input
ripple current requirements and output voltage ripple
while easing component selection and layout difficulties.
The Quick-PWM control scheme provides instantaneous
response to fast-load current steps. The MAX8760
includes active voltage positioning with adjustable gain
and offset, reducing power dissipation and bulk output
capacitance requirements.
The MAX8760 is intended for two different notebook CPU
core applications: stepping down the battery directly or
stepping down the 5V system supply to create the core
voltage. The single-stage conversion method allows this
device to directly step down high-voltage batteries for the
highest possible efficiency. Alternatively, two-stage con-
version (stepping down the 5V system supply instead of
the battery) at a higher switching frequency provides the
minimum possible physical size.
The MAX8760 complies with AMD’s desktop and mobile
CPU specifications. The switching regulator features soft-
start and power-up sequencing, and soft-shutdown. The
MAX8760 also features independent four-level logic inputs
for setting the suspend voltage (S0, S1).
