DESCRIPTION
LTM4607EV
High Efficiency PolyPhase
Buck-Boost Power Supply
Demonstration circuit DC1601B is a PolyPhase
®
power
supply featuring the LTM
®
4607 power module, a complete
high efficiency switching mode buck-boost power supply.
The DC1601B input voltage range is from 6V to 36V and
is capable of delivering high power through paralleled
LTM4607 modules. The demo circuit can deliver up to 10A
ofoutputcurrentfortwoparalleledmodules(DC1601B-A),
15A for three paralleled modules (DC1601B-B) and up
to 20A for four paralleled modules (DC1601B-C). The
DC1601B demonstrates that paralleling modules is easy
and reliable.
The output voltage for the board is 12V. The rated load
current per module is 5A in boost mode, however cur-
rent derating may be necessary under certain VIN, VOUT,
frequency, and thermal conditions. An onboard external
clock is provided for synchronization and interleaving of L, LT, LTC, LTM, Linear Technology, PolyPhase and the Linear logo are registered trademarks
of Linear Technology Corporation. All other trademarks are the property of their respective
owners.
phases to minimize input and output ripple. An internal
phase-locked loop allows the LTM4607 to be synchro-
nized to an external clock within the range of 200kHz to
400kHz. The LTM4607 default switching frequency on the
DC1601B is set to 300kHz through the onboard LTC6902
clock generator which interleaves the paralleled phases.
The frequency and phase separation set by the LTC6902
are resistor programmable.
These features, including the availability of the LTM4607 in
a compact thermally enhanced 15mm × 15mm × 2.8mm
LGA package make the demonstration circuit ideal for
use in high density point of load regulation applications.

Figure 1
Demonstration circuit DC1601B is easy to setup to evaluate
the performance of paralleled LTM4607 modules. Please
refer to Figure 1 for proper measurement equipment setup
and follow the procedure below:
1. With power off, connect the input power supply, load,
and meters as shown in Figure 1. Preset the load to 0A
and VIN supply to be 0V. Place jumpers in the following
positions for a typical 12VOUT application:
JP2 JP1 JP3
MODE RUN START
CCM OFF SSO
2. Turn on the power at the input. Increase VIN to 18V
(Do not hot-plug the input supply or apply more than
the rated maximum voltage of 36V to the board or the
modules may be damaged).
3. Set the run pin jumper (JP1) to the ON position. The
output voltage should be regulated. The output voltage
meter should read 12V ±2% (11.76V to 12.24V).
4. Vary the input voltage from 6V to 36V and adjust the
load current from 0A to 10A (for DC1601B-A), 0A to
15A (for DC1601B-B), 0A to 20A (for DC1601B-C).
VOUT should remain regulated at 12V ±2% (11.76V to
12.24V). Observe the load regulation, efficiency and
other parameters.
5. Set the load current to 0A. Set the RUN pin jumper
(JP1) to the OFF position. Turn off input supply before
disconnecting the circuit.
