• Manufacturer Part Number: MAX17039EVKIT+
• Description: Power Management IC Development Tools Dual-Output 3-Phase + 1 Phase Quick-PWM Controller for VR12/IMVP-7
• Manufacturer: Maxim Integrated
• Series: MAX17039r

The MAX17039 kit also demonstrates the MAX17007A
I/O power-solution circuit.
This DC-DC converter steps down high-voltage batteries
to generate low-voltage core or chipset/RAM bias sup-
plies in notebook computers. The MAX17007A circuit
generates two independent I/O voltages (VTT1 and
VTT2) from a 7V to 20V battery-input range. VTT1 and
VTT2 are configured for 1.05V output voltages. The VTT1
output delivers up to 6A and the VTT2 output delivers up
to 21A. The VTT1 and VTT2 outputs operate at 270kHz
and 330kHz switching frequencies, respectively. Both
outputs can be configured for other voltages by chang-
ing resistor R140, R141, R152, and R153 values. Refer to
the MAX17007A IC data sheet for more details.

The outputs can also be combined to operate as a
2-phase, high-current, single-output regulator. In this
mode the output is configured for either a preset, adjust-
able, or dynamically adjustable output voltage using
REFIN1. Refer to the Combined-Mode Operation (FB2 =

details.
The MAX17007A provides access to the device’s enable
control pins (EN1 and EN2) through jumpers JU15 and
JU16, respectively. EN1 is used to control the VTT1 out-
put and EN2 is used to control the VTT2 output. When
in combined mode, EN1 is used for output control and
EN2 must be connected to GND. Tables 4 and 5 list the
options for each output-enable pin.
