Detailed Description
The MAX8809A/MAX8810A synchronous, 2-/3-/4-
phase, step-down, current-mode controllers with inte-
grated dual-phase MOSFET drivers provide flexible
solutions that fully comply with Intel VRD11/VRD10 and
AMD K8 Rev F CPU core supplies. The flexible design
supplies load currents of up to 150A for low-voltage
CPU core power supplies.
The MAX8809A is suitable for 2- or 3-phase core sup-
ply applications. With an integrated dual-MOSFET dri-
ver, the MAX8809A offers a single-chip IC solution for
dual-phase core supplies. Together with the MAX8552,
a high-performance single-phase MOSFET driver, the
MAX8809A also supports 3-phase core supplies.
Similarly, the MAX8810A features a single IC solution
for dual-phase core supplies. It also features two-IC
solutions for 3- or 4-phase core supplies by adding a
single MOSFET driver (MAX8552) or a dual-MOSFET
driver (MAX8523).
Both the MAX8809A and MAX8810A fully comply with
Intel VRD11, Extended VRD10, and the AMD K8 Rev F
VID codes. The SEL input allows the user to select the
architecture specifications.
Clock Frequency (OSC)
An external resistor, R OSC , from OSC to GND sets the
internal clock frequency of the MAX8809A/MAX8810A.
A 1% resistor is recommended to maintain good fre-
quency accuracy. The internal clock frequency sets the
per-phase switching frequency. The selection of switch-
ing frequency per phase is influenced by factors such
as the switching speed of the MOSFETs, the inductor’s
core material, different types of input and output capac-
itors, and the available board space. Once the per-
phase switching frequency is selected, the internal
clock frequency is determined using the procedure in
the Setting the Switching Frequency section.
