1-Phase Quick-PWM
Intel IMVP-6.5/GMCH Controllers
General Description
The MAX17528 comprises 1-phase Quick-PWM ? step-
down VID power-supply controllers for Intel notebook
CPUs. The Quick-PWM control provides instantaneous
response to fast-load current steps. Active voltage
positioning reduces power dissipation and bulk output
capacitance requirements and allows ideal positioning
compensation for tantalum, polymer, or ceramic bulk
output capacitors.
The MAX17528 is intended for two different notebook
CPU/GPU core applications: either bucking down the bat-
tery directly to create the core voltage, or bucking down
the +5V system supply. The single-stage conversion
method allows these devices to directly step down high-
voltage batteries for the highest possible efficiency.
Alternatively, 2-stage conversion (stepping down the
+5V system supply instead of the battery) at higher
switching frequency provides the minimum possible
physical size.
A slew-rate controller allows controlled transitions
between VID codes. A thermistor-based temperature
sensor provides programmable thermal protection. A
current monitor provides an analog output current pro-
portional to the processor load current.
