Kit Introduction
The MC34700 is a four output DC to DC regulator for multi-rail applications. The
Evaluation Board is designed to provide the user with the ability to configure the part using
a single 9V to 18V input supply, a dual supply, or with each regulator supplied individually.
The Evaluation Board has three buck regulators that are setup for outputs of 3.3V at 1.5A,
2.5V at 1.25A and 1.25V at 1.25A and an LDO with a 0.9V at 400mA output. Inputs to
enable each output channel are provided as well as a Power Good LED indicator.

When operating from a single input supply be aware that CH2 and CH3 are run off the
output of CH1 and that the LDO is run off the output of CH3. As a result, the output current
available from CH1 is not the full 1.5A, but the current remaining after supplying VIN2 and
VIN3. Similarly the current available for CH3 is not the full 1.25A.

Using the Hardware
Use the following steps to verify that the Evaluation Board is operational:
a) Verify jumpers are installed as shown in Jumper Connections Section. Use the
default settings.
b) Check polarity and connect a 12V, 2A supply to VIN1 terminal.
c) Check 12V supply current with all the regulators disabled. The supply current should
not exceed 15mA.
d) Enable CH1 by moving EN1 jumper to 1-2 position. Verify 3.3V channel is operating
by measuring voltage at VOUT1 terminal. VOUT1 is typically 3.38V.
e) Enable CH2 by moving the EN2 jumper to the 1-2 position. Verify the 2.5V channel is
operating by measuring the voltage at the VOUT2 terminal. VOUT2 is typically 2.49V.
f) Enable CH3 by moving EN3 jumper to 1-2 position. Verify that the 1.25V channel is
operating by measuring the voltage at the VOUT3 terminal. VOUT3 is typically 1.28V.
g) Enable LDO by moving EN_LDO jumper to 1-2 position. Verify 0.9V channel is
operating by measuring voltage at VOUT_LDO terminal. VOUT_LDO is typically
0.9V.
h) If all the regulators are up and running, verify that the PGOOD LED (D2) is on.
After board verification, it can be reconfigured and tested per system requirements.

Using the Hardware
6.2
PGOOD
The evaluation board includes a status LED (D2), that indicates all the regulators are
operating and no faults have occurred. The FET, Q1, is required for signal inversion and
to drive the LED current. The resistor, R26, limits the LED current.
The jumper (PGOOD_LED) disconnects the status LED for making efficiency and
quiescent current measurements. The status LED is connected to the output of CH1 when
the jumper is installed.
The test point PGOOD is the open drain output of the PGOOD pin. It is pulled up to
VGREG by resistor R25.
6.3
Switch Nodes
The evaluation board includes test points for monitoring the switch nodes of DC/DC 1, 2
and 3. The test points are located close to the output inductors of each channel. The
switch nodes can be used to measure switching frequency, duty cycle, phase, and switch
times.
6.4
Power Input Voltage
The power input voltage for DC/DC1 (VIN1) is connected to the VIN1 terminal block. The
VIN1 input is bypassed with bulk capacitors C27 and C28, and is connected to the IC input
pin (VIN) by an RC filter, R2 and C20.
Power inputs for DC/DC 2, and DC/DC 3 (VIN2, and VIN3) can be connected to the
AUX_IN terminal or the output of DC/DC 1. By setting the jumpers (VIN2, and VIN3) to
position 2-3, each regulator can be powered from the AUX_IN. By setting the jumpers to
position 1-2, each regulator can be powered from the output of DC/DC 1.
The power input voltage for the LDO (LDO_VIN) can be connected to the AUX_IN
terminal or the output of DC/DC 3. By setting the jumper (LDO_VIN) to position 2-3, the
LDO can be powered from the AUX_IN. By setting the jumper to position 1-2, the LDO can
be powered from the output of DC/DC 3. The AUX_IN input is bypassed with bulk
capacitors C30 and C31.
For single supply operation, set VIN2, VIN3 and LDO_VIN to position 1-2. This connects
the input of DC/DC 2 and DC/DC 3 to the output of DC/DC 1 and the LDO input to the
output of DC/DC 3.
For dual supply operation, set VIN2, and VIN3 to position 2-3. This connects the input of
DC/DC 2 and DC/DC 3 to the AUX_IN terminal block. Set the LDO_VIN to either position
depending on the application to connect the LDO input to the output of DC/DC 3 or the
AUX_IN terminal.
If each regulator needs to powered from a separate supply, two of the input power jumpers
can be removed and an external supply connected directly to header position 2. Select

Using the Hardware
the regulators with the lowest output power to connect directly to the header pin. The other
two regulators are powered from VIN1 and AUX_IN.
6.5
Enables and Cascaded Sequencing
The enable headers are currently configured for a simple enable/disable function. Setting
the jumper to position 1-2 connects the enable pin to the VGREG output, enabling the
respective regulator. Removing or setting the jumper to position 2-3 connects the enable
pin to ground, disabling the respective regulator.
However, the board has provisions to add a resistor divider to each enable pin which
allows cascaded sequencing. Resistors R11, R12, R15, and R17 are installed and are
10K Ohm. By installing resistors R13, R14, R16, and R18 a voltage divider is formed at
each enable pin. By setting the resistor divider of each enable, the voltage of the enable
pin has to reach its’ threshold level before the regulator in the sequence is enabled. Note
that the jumpers need to be removed and the output of the regulator in the previous
sequence position be connected to pin 2 of the enable header. See the data sheet for
more details on calculating the divider.
6.6
Leakage Current
DC/DC 2 and DC/DC 3 each have ~400uA of leakage current that can cause the output
to float up if there is not enough load current in the application. 1K Ohm resistors are
installed at R36 and R37 (located on the bottom side of the PC board) to prevent VOUT2
and VOUT3 from floating when these channels are disabled.
The 1K load can be removed if there is a minimum load of at least 4mA present on VOUT2
and VOUT3.
